Z score = ( X - mean )/sd
here,
mean = 500
sd = 100
A. 650
Z score = ( X - mean )/sd
Z score = ( 650 - 500 )/100
Z score = 150/100
Z score = 1.5
B. 500
Z score = ( X - mean )/sd
Z score = ( 500 - 500 )/100
Z score = 0/100
Z score = 0
C. 450
Z score = ( X - mean )/sd
Z score = ( 450 - 500 )/100
Z score = -50/100
Z score = -0.5

A sample of 10 students record their scores on the final exam for their statistics class. The mean of the sample is 81 with sample standard deviation 7 points. Analysis of the 10 sample values indicated that the population is approximately normal. We wish to find the 95% confidence interval for the population mean test scores. What is the confidence level, c? Which of the following is correct? To find the confidence interval, a z-critical value should be used because...
