In 145 cases, guidelines were not followed, and the cases had a standard deviation of 16.36 months (same reference as previous question). Assuming the population standard deviation for all cases of the same nature was 11 months, test the claim the standard deviation for the 145 non-guideline cases is the same as the population standard deviation of 11 months with = .05.

Step 1: Write hypothesis

H0:

H1:

Step 2:Identify type of test by tails and if it is t or chi-square test.

Step 3: Find the P-value or critical value(s) and test statistic.

Step 4: State decision and conclusion
