A house cleaning service claims that it can clean a four-bedroom house in less than 2 hours. A sample of n=16n=16 houses is taken, and the sample mean is found to be 1.97 hours and the sample standard deviation is found to be 0.1 hours.
Write the interpretation base on the decision. A. There is enough evidence to reject the claim B. There is not enough evidence to support the claim C. There is enough evidence to support the claim D. There is not enough evidence to reject the claim

Studdy Solution
Make a decision:
- Compare the test statistic to the critical value: 1.2-1.2 is greater than 1.753-1.753. - Since the test statistic is not in the critical region, we fail to reject the null hypothesis.
Interpretation: D. There is not enough evidence to reject the claim.
