<h3>Answer: B) 31.348</h3>
======================================
Work Shown:
We will never use the alpha = 0.05 value when computing the test statistic. So we can ignore alpha for this particular problem.
-------
n = 40 is the sample size.
s = 2.6 is the sample standard deviation
= sigma = 2.9 is the population standard deviation (ie the claimed standard deviation for all the pay phones)
Test Statistic for chi-square
The answer is 11 if you use PEMDAS! Here is my work:
9+4-4+2 = I multiplied and divided first
13-4+2....9+2....11
Hope this helped :))
