Answer:
Step-by-step explanation:
If the z statistic does not lie within the critical region, you cannot reject the null hypothesis but neither can you necessarily accept it.
What you can do is reject the alternate hypothesis.
The valid conclusion based on the given results is; One can reject the alternate hypothesis.
What is the Conclusion of the Hypothesis?We are told that;
z-statistic = 2.1
Now, the critical z-values were -1.96 and 1.96
Since our z-statistic does not lie within the critical values region, it means that there is not enough evidence to reject the null hypothesis at the given significance level. However, it means that we can reject the alternate hypothesis.

A set of magical wand prices are normally distributed with a mean of 50 dollars and a standard deviation of 4 dollars. A blackthorn wand has a price of 45.20
Complete Question
A set of magical wand prices are normally distributed with a mean of 50 dollars and a standard deviation of 4 dollars. A blackthorn wand has a price of 45.20. What proportion of wand prices are lower than the price of the blackthorn wand? You may round your answer to four decimal places
Answer:
0.1151
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = $45.20
μ is the population mean = $50
σ is the population standard deviation = $4
We are solving for x < 45.20
Hence:
z = 45.20 - 50/4
z = -1.2
Probability value from Z-Table:
P(x<45.20) = 0.11507
Approximately to 4 decimal places = 0.1151
Therefore, the proportion of wand prices that are lower than the price of the blackthorn wand is 0.1151

Ashley has two jobs: mowing lawns and babysitting. She earns $10 per hour mowing lawns (x) and $8 per hour babysitting (y). And she wants to earn at least $160 per week. Rewrite the inequality from in slope-intercept form
Answer:
18x ≥ 160
Step-by-step explanation:
Ashley has two jobs: mowing lawns and babysitting. She earns $10 per hour mowing lawns (x) and $8 per hour babysitting (y). And she wants to earn at least $160 per week.
Let the number of hours = x
At least = Greater than or equal to
Slope intercept form
= y = mx + c
y = $160
Hence
10x + 8x ≥ 160
18x ≥ 160

If 3 runners has a mean running time of 6.2, 7.4 and.6.9 and had an interquartile range of 1.1, .02 and .08 who would be the fastest runner
Answer:
The runner with a mean running time of 6.2
Step-by-step explanation:
The value range parameters of the three runners are;
The mean running time of the runner, A = 6.2
The mean running time of the runner, B = 7.4
The mean running time of the runner, C = 6.9
The interquartile range of the runner, A = 1.1
The interquartile range of the runner, B = 0.02
The interquartile range of the runner, C = 0.08
Whereby the number of running times for the 3 runners is large, and with the assumption that distribution of the mean is normal, we have
The mean = The mode of the data
Therefore, the minimum, and maximum running time of the runners are;
Runner A;
Minimum running time = 6.2 - 1.1 = 5.1
Maximum running time = 6.2 + 1.1 = 7.3
Runner B;
Minimum running time = 7.4 - 0.02 = 7.38
Maximum running time = 7.4 + 0.02 = 7.42
Runner C;
Minimum running time = 6.9 - 0.08 = 6.82
Maximum running time = 6.9 + 0.08 = 6.98
The fastest runner has the lowest running time;
Therefore, the fastest runner is runner A with a mean running time of 6.2 with a minimum running time of 5.1

Step-by-step explanation:
Mary, Josephine, Quinn, Taylor, Max, and Taylor went out to lunch and the total bill was $72. Mary puts in $20 , and Josephine puts in $12. The rest of the group splits the bill equally. Which equation and solution represent the amount a that each of the remaining people pay?
Answer:
i. The equation required = [tex]\frac{remaining amount of the bill}{remaining number of people}[/tex]
ii. Remaining people would pay $10 each.
Step-by-step explanation:
Total number of people involved = 6
Total bill of their lunch = $72
Mary and Josephine paid = $20 + $12
= $32
The remaining bill to be paid = $72 - $32
= $40
The rest of the group = 4
Splitting the remaining bill equally,
the equation required = [tex]\frac{remaining amount of the bill}{remaining number of people}[/tex]
= ($40) ÷ 4
= $[tex]\frac{40}{4}[/tex]
= $10
The amount that each of the remaining people would pay is $10.

HOPE THIS HELPS!!20 divided by 2 1/3 = 8.57
8 batches is the answer.
Answer:
Actually, 20 divided by 2 1/3 equals 8.57 repeating (8.571428...), which can be rounded to 8.57 to two decimal places.
To see why, we can convert the mixed number 2 1/3 to an improper fraction:
2 1/3 = (2 * 3 + 1) / 3 = 7/3
Then, we can rewrite the division as a fraction and simplify:
20 / (7/3) = 20 * (3/7) = 60/7 = 8.571428...
So, 20 divided by 2 1/3 is approximately 8.57.

convert 4 miles into cm. show your work
Answer:
643737.6
Step-by-step explanation:
1 inch is 2.54 centimeters. 2.54 centimeters is 1 inch. 12x2.54 =30.48. 30.48 is equal to one foot because 12 inches are in 1 foot and one inch is 2.54 centimeters. 1 yard is 3 feet so 30.48x3=91.44. 1 yard is equal to 91.44 centimeters. 1 miles is 1760 yards so 91.44x1760= 160934.4. 1 mile is equal to 160934.4 centimeters. Since 1 mile is equal to 160934.4 centimeters, you have to multiply 160934.4 by 4 to get 4 miles. 160934.4x4=643737.6 and this is your final answer. Therefore, 4 miles is equal to 643737.6 centimeters.

8 A right rectangular prism is completely filled with small cubes. Each small cube
has edges that are 1/4 in. long. The volume of the prism is 5 in.. How many cubes
does it take to fill the prism?
A-20
B-64
C-125
D-320
The number of cubes in the rectangle prism will be 320. Then the correct option is D.
What is the volume of the rectangular prism?Let the prism with a length of L, a width of W, and a height of H. Then the volume of the prism is given as
V = L x W x H
A right rectangular prism is completely filled with small cubes. Each small cube has edges that are 1/4 inches long. The volume of the prism is 5 inches.
Let 'n' be the number of cubes. And all the sides of the cube are congruent. Then the volume of each cube is calculated as,
Volume of cube = (1/4) x (1/4) x (1/4)
Volume of cube = 1 / 64 cubic inches
The volume of the rectangle and the volume of small 'n' cubes will be equal. Then we have
Volume of 'n' cube = Volume of a rectangle
(1 / 64) n = 5
n = 5 x 64
n = 320
The number of cubes in the rectangle prism will be 320. Then the correct option is D.
More about the volume of the rectangular prism link is given below.
