Basic Computation: Testing M1 2 M2 A random sample of 49 measurements from a population with population standard deviation 3 had a sample mean of 10. An independent random sample of 64 measurements from a second population with population standard deviation 4 had a sample mean of 12. Test the claim that the population means are different. Use level of significance 0.01. (a) Check Requirements What distribution does the sample test statistic follow

Answers

Answer:

The sample statistics follows a standard normal distribution since the sample size are large enough.

Step-by-step explanation:

Given that:

First population:

Sample size [tex]n_1[/tex] = 49

Population standard deviation [tex]\sigma_1[/tex]  = 3

Sample mean [tex]\overline x _1[/tex]= 10

Second population:

Sample size [tex]n_2[/tex] = 64

Population standard deviation [tex]\sigma_2[/tex]= 4

Sample mean [tex]\overline x_2[/tex]= 12

The sample statistics follows a standard normal distribution since the sample size are large enough.

The null and alternative hypotheses can be computed as:

[tex]\mathbf{H_o:\mu_1=\mu_2}[/tex]

[tex]\mathbf{H_1:\mu_1\ne\mu_2}[/tex]

Level of significance  = 0.01

Using the  Z-test statistics;

[tex]Z = \dfrac{\overline x_1 - \overline x_2}{\sqrt{\dfrac{\sigma_1^2}{n_1} + \dfrac{\sigma_2^2}{n_2}}}[/tex]

[tex]Z = \dfrac{10- 12}{\sqrt{\dfrac{3^2}{49} + \dfrac{4^2}{64}}}[/tex]

[tex]Z = \dfrac{-2}{\sqrt{\dfrac{9}{49} + \dfrac{16}{64}}}[/tex]

[tex]Z = \dfrac{-2}{\sqrt{0.18367 +0.25}}[/tex]

[tex]Z = \dfrac{-2}{\sqrt{0.43367}}[/tex]

[tex]Z = \dfrac{-2}{0.658536}[/tex]

Z = - 3.037

Z [tex]\simeq[/tex] - 3.04

The P-value = 2P (z < -3.04)

From the z tables

= 2 × (0.00118)

= 0.00236

Thus, since P-value is less than the level of significance, we fail to reject the null hypotheses [tex]H_o[/tex]

Answers

Answer:

its a).4

Step-by-step explanation: 60 divided by 15= 4 you can use a calculator to check if im right if you dont trust me

The answer would be 4 if the number expression is 60 ÷ 15 after using the arithmetic operation, option (A) 4 is correct.

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.

It is given that:

The number expression is:

60 ÷ 15

Using model:

= (15 + 15 + 15 + 15) ÷ 15

= 1 + 1  + 1 + 1

= 4

Thus, the answer would be 4 if the number expression is 60 ÷ 15 after using the arithmetic operation, option (A) 4 is correct.

A polygon is graphed on a coordinate plane, with a vertex located at
a point represented by (x,y).
The polygon is dilated with a scale factor, a , with the origin as the
center of dilation. The dilated image of the polygon is larger than
the polygon.
Which statement is true?

Answers

Answer:

a is greater than 1

Step-by-step explanation:

Let the two polygons be represented as  A and B.

Where A is the original polygon and B is the image of A

Such that

Polygon A has vertex (x,y) and scale factor = a

From the question, we understand that polygon B is bigger than A

When the dilated image (polygon B) is bigger than the original image (polygon A), then the scale factor is greater than 1.

Take for instance.

One of the coordinate point of polygon A is (2,4)

The corresponding coordinate point of polygon B will be greater than (2,4) because a is greater than 1.

Take a as 2:

The corresponding point on Polygon B would be 2 * (2,4) = (4,8)

What is the present value of ₱30,000 due in 27 months at 3% compounded annually?

Answers

Answer:

32,063.06

Step-by-step explanation:

the formula for compound interest: [tex]A = P(1+\frac{r}{n})^{nt\\}[/tex]

so to use this you are essentially solving for a.

p is the principle (or initial) amount deposited.

r is the rate (in percent)

n is the number of time periods compounded (like annually, monthly, weekly, or daily)

t is the time period (in years)

In this instance the formula looks like: [tex]A = 30,000(1+\frac{0.03}{1})^{1*2.25}[/tex]

You then solve for A using the formula. It is important to remember to use the order of operations

Item 12
The graph represents the height y, in feet, above the ground of a water balloon x seconds after it is dropped from a window.



Which statement is true?

Select each correct answer.




The maximum height of the water balloon occurs at x = 0.

The water balloon is in the air for 2 s.

The water balloon hits the ground in 64 s.

The water balloon rises above 64 ft before falling toward the ground.

The maximum height of the water balloon is 64 ft.

Answers

Answer:

O The maximum height of the water balloon occurs at x = 0.    

O The water balloon is in the air for 2 s.    

O The maximum height of the water balloon is 64 ft.

Step-by-step explanation:

Firstly, by simply looking at the x axis on the graph (time), you will see that it starts at 0 and the 64 ft maximum height is aligned with the starting point of 0 seconds.  

The graph also shows (x axis) the 'time' represented, and as the height rapidly decreases the graph eventually reaches the 2 second mark, going no further and no lower.  

Finally, the graph shows (y axis) the peak of the water balloon's height is 64 ft, as it is the highest number reached while the water balloon was airborne.

The following statement is True.

The maximum height of the water balloon occurs at x = 0.The water balloon is in the air for 2 s.The maximum height of the water balloon is 64 ft.

A true statement to be chosen from the following.

What is a graph?

The graph is a demonstration of curves  that gives the relationship between the x and y-axis.

From the graph, the following points are to be noted.
The water balloon is at 64 ft at x = 0.
The water balloon takes 2 sec to reach y = 0.
The water balloon has a maximum height of x = 0.

Thus, points 1,2, and 5 are true.

Determine the total surface area of each right triangle-based prism

Answers

Answer:

small prism: 630 m²large prism: 2520 m²

Step-by-step explanation:

The total surface area of the prism is the sum of the base area and the lateral area. The base area is made up of two right triangles, so will be the product of the triangle leg dimensions. The lateral area is made up of three rectangles whose width is that of the prism and whose equivalent length is the perimeter of the triangle base.

For the smaller prism, the area is ...

  (20 m)(21 m) +(3 m)(20 m + 21 m + 29 m) = 420 m² +210 m² = 630 m²

The larger prism is similar, with a scale factor of 2, so its area will be 2² = 4 times that of the smaller prism:

  4×630 m² = 2520 m²

__

In summary, the total surface area of each prism is ...

small prism: 630 m²large prism: 2520 m²

A local insurance agent visits the high school and tells the students that his insurance company will give students a 7% discount on liability insurance, PIP. comprehensive insurance, and collision insurance for three years if they take a defensive driving course. Maria spends $1,437.00 on her auto insurance annually.

Answers

The question is vague, but I'll try and help.

Answer:

She saves $100.59 a year.

Step-by-step explanation:

Saving 7% of $1,437.00 each year.

7% of $1,437.00 (0.07 x $1,437.00) = $100.59

If it asks how much she saves over a certain number of years, just multiply 100.59 times how many years it asks for. Hope this helps.

The required, if Maria takes the defensive driving course and receives the 7% discount on her auto insurance, she will save a total of $301.77 over three years.

What is the investment?

Investment is defined as when an individual spends money on something that returns him or her higher money than the money they invested.

Here,
If Maria spends $1,437.00 on her auto insurance annually and she takes the defensive driving course, she will get a 7% discount on her liability insurance, PIP, comprehensive insurance, and collision insurance for three years.

To calculate the amount of the discount, we first need to find 7% of $1,437.00:

Discount = 0.07 × $1,437.00 = $100.59

So, the amount of the discount that Maria will receive annually is $100.59.

To find the total savings over three years, we multiply the annual discount by three:

Total savings = $100.59 × 3 = $301.77

Therefore, if Maria takes the defensive driving course and receives the 7% discount on her auto insurance, she will save a total of $301.77 over three years.
