HYPOTHESIS TESTING Due to the Covid-19 pandemic. Many shops went online. One of them is an online restaurant. It claims that the mean delivery time for food orders is less than 120 minutes with a standard deviation of 30 minutes. Is there enough evidence to support this claim at a 0.05 significance level if 49 orders were examined with a mean of 100 minutes? Use this Format 1. Formulate Ho and Ha. 2. Determine the test to be used. 3. Set the significance level. Determine the tabulated or critical value (TV) for the test.

Use this Format
1. Formulate Ho and Ha.
2. Determine the test to be used.
3. Set the significance level. Determine the tabulated or critical value (TV) for the test.
4. Computation
5. Compare computed value (CV) with the tabulated or critical value (TV). Then, make a decision.
a. Reject Ho and Accept Ha if |CV| ≥ |TV|.
b. Accept Ho and Reject Ha if |CV| < |TV|.
6. Conclusion.
