The parameter used in the probability is the average number of students represented by u.
How to calculate the probability?
The confidence interval based on the information will be:
= 3.85 - 2.09(1.348 / ✓20)
= 3.22
Also, 3.85 + 2.09(1.348 / ✓20) = 4.48
The confidence interval simply means that one is 95% confident that the true mean is between 3.22 and 4.48.
For a width of 25, the length will also be 25, so the area is 25² = ...
625.
_____
The rule is
area = width×(50 -width)

Answer:
The testing statistic is -2.237
Step-by-step explanation:
Test statistic (z) = (sample mean - population mean) ÷ (population standard deviation/√n)
sample mean = 6.3 ounces
population mean = 6.4 ounces
population standard deviation = 0.2 ounces
n (sample size) = 20
z = (6.3 - 6.4) ÷ (0.2/√20) = -0.1 ÷ 0.0447 = -2.237
D. (9x-4)^2
You can find this by taking the square roots of the outside numbers and multiplying them by each other and 2 to see if they equal the middle number.
