Need help creating a null and alternative hypothesis for the following problem:

Problem: Case Closure time is very high.

Practical Hypothesis: Error logging is present in the part of the product in which the case was raised

running a 2 sample test assuming equal variances to test to see if error logging plays a factor in case closure time.

Answer #1

The appropriate hypotheses for the problem statement would be as below.

Null Hypothesis H0: Average closure time for cases with error logging is equal to the average closure time for cases without error logging.

Alternative Hypothesis H0: Average closure time for cases with error logging is greater than the average closure time for cases without error logging.
