Answer:

The decision rule is  

Fail to reject the null hypothesis

 The conclusion is  

There is no sufficient evidence to show that  the  designer's claim of a better shoe is supported by the trial results.

Step-by-step explanation:

From the question we are told that

  The population mean is  [tex]\mu = 15 \ months[/tex]

   The sample size is  n =  25

   The sample mean is  [tex]\= x = 17 \ months[/tex]

   The standard deviation is  [tex]s = 5.5 \ months[/tex]

Let assume the level of significance of this test is  [tex]\alpha = 0.05[/tex]

    The null hypothesis is  [tex]H_o : \mu = 15[/tex]

     The alternative hypothesis is  [tex]H_a : \mu > 17[/tex]

Generally the degree of freedom is mathematically represented as  

         [tex]df = n -1[/tex]

=>       [tex]df = 25 -1[/tex]

=>       [tex]df = 24[/tex]

Generally the test statistics is mathematically represented as

        [tex]t = \frac{\= x- \mu }{\frac{s}{\sqrt{n} } }[/tex]

=>   [tex]t = \frac{ 17 - 15 }{\frac{5.5}{\sqrt{25} } }[/tex]

=>   [tex]t = 1.8182[/tex]

Generally from the student t distribution table the probability of obtaining   [tex]t = 1.8182[/tex] to the right of the curve at a degree of freedom of [tex]df = 24[/tex]  is  

    [tex]p-value = P(t > 0.18182 ) = 0.4286[/tex]

From the value obtained we see that  [tex]p-value > \alpha[/tex] hence

The decision rule is  

Fail to reject the null hypothesis

 The conclusion is  

There is no sufficient evidence to show that  the  designer's claim of a better shoe is  supported by the trial results.

Answer:

[tex]\frac{1}{16}[/tex]

Step-by-step explanation:

[tex]6\frac{1}{4}=\frac{25}{4}[/tex]

since percent means divided by 100

[tex]\frac{25}{4} *\frac{1}{100}[/tex]

=[tex]\frac{1}{16}[/tex]

Answer:

288

Step-by-step explanation:

Evaluate Using the Given Value

2 (a (2b + 3c)) for a = 8 , b = 3 , and c = 4

Replace the variable a with 8 in the e xpression.

2 ((8) (2b + 3c))

Replace the variable b with 3 in the expression.

2 ((8) (2 (3) + 3c))

Replace the variable c with 4 in the expression.

2 ((8) (2 (3) + 3 (4)))

Simplify each term.

Multiply 2 by 3.

2 (8 (6 + 3 (4)))

 Multiply 3 by 4.

2 (8 (6 + 12))

Simplify the expression. Tap for fewer steps...

Add 6 and 12.

2 (8 ⋅ 18)

 Multiply 8 by 18.

2 ⋅ 144

 Multiply 2 by 144.

Answer:

Step-by-step explanation:

66-95-99.7 rule

standard deviation is 10. meaning that it'll deviate twice meaning you use the 95%

95% of 200 is 190, so 190 students had scores between 40 and 80

Answer:

24000 regular grams

Answer: 24000

Step-by-step explanation: because you have to  multiply the mass value by 1000

Answer: Yes

Step-by-step explanation: We're going to have to substitute

in the coordinates of that ordered pair into the equation.

I am going to substitute in the x and substitute in the y.

So it's really 5(2) + 3(-3) = 1.

From here it should be pretty straightforward,

all we are doing is evaluating the statement.

Simplifying on the left we have 10 + -9 = 1 or 1 = 1.

Now we know that the ordered pair (2, -3) satisfies this equation.

Answer:

it's 3n + 18 and 10 + 3n +8

Answer:

(1) 56 miles/hour

Step-by-step explanation:

We need to find the average rate of change from t = 2 to t = 9.

At t = 2 hours, d = 106 miles.

At t = 9 hours, d = 498 miles.

The average rate of change in function f(x) from x = a to x = b is

[f(b) - f(a)]/(b - a)

average rate of change from t = 2 to t = 9 =

(498 - 106)/(9 - 2) = 392/7 = 56

Answer: (1) 56 miles/hour

Answer:

Linear function: y = 24x + 25

Step-by-step explanation:

24 hours = 1 day

30 days = 1 month

0.15 x 24 = 6

30 x 6 = 180

180 + 25 = 205

Linear function: y = 24x + 25

Hope this helps! :)

Answer:

The plane is traveling at 160 km/h

Step-by-step explanation:

This is because if the first plane is traveling at 160 and flies for 5 hours it'll travel 800 km. then the second plane will have to catch up in 4 hours since it left an hour late, this means traveling at 160 km with an extra 40 km in 4 hours will get it to the first plane at 800 km in the 4 hours given

There are two, the first one is 4 and the second is 132

Step-by-step explanation:

36 divided by 3 is 12, so 48 divided by 12 would give us the answer 4. In the last one, you multiply 11 by 12 instead.

Step-by-step explanation:

the second one is 132 uuwwuu

Answer:

Coordinates of point C after dilation with a scale factor of 5, centered at the origin will be: C'(10, 5)

Step-by-step explanation:

Given the point C

A dilation with a scale factor of 5 means the size of the coordinates of the image of point P will be 5 times larger than than the original coordinates of point C.

Thus, the rule of dilation by a scale factor 5 is:

(x, y)  →  (5x, 5y)

C(2, 1)  →  (5x, 5y) = (5(2), 5(1)) = C'(10, 5)

Therefore, coordinates of the point C after dilation with a scale factor of 5, centered at the origin will be: C'(10, 5)
