Question 1: A sample of 30 cookies is taken to the test the claim that each cookie contains at least 9 chocolate chips. The average number of chocolate chips per cookie in the sample was 7.8 with a standard deviation of 3. Test the following hypothesis. Therefore, you should realize that this is the case where standard deviation is calculated from the sample, which means this is a sigma (σ) unknown case.
??0: ?? ≥ 9
??0: ?? < 9
Using the critical value approach, test the hypotheses at the 5% level of significance.
Question 2: A sample of 49 CBU students was selected in order to determine whether the average number of times students pray a week is significantly different from 21. The average number of times tudents pray in the sample was 23 with a standard deviation of 3.5. This is a sigma (σ) unknown ase
a. Test the following hypotheses at the 5% level of significance.
??0: ?? = 21
??0: ?? ≠ 21
b. Provide the positive impacts of daily prayer using bible verses. This is an open-ended question.
