- Express the null hypothesis H0 and the alternative hypothesis Ha in notation form in the following scenarios. 1. The mean annual income of workers who are college graduates is greater than Php100,000 a year. 2. The percentage of women who watches sports on TV is not 40% as claimed by a researcherIf Ho is true, and we reject the Null hypothesis. this is called?A golf pro shop is deciding whether to carry a new, more expensive line of golf balls that claim to travel further. To test the new balls, the pro shop manager asked the club’s golf pro to hit 100 of the top selling brand of balls and 100 of the new balls. The distance traveled by both the new and current balls was recorded. For this scenario, which of the following would be the proper set of hypotheses? a. H0: µD = 0 H1: µD > 0 b H0: µD = 0 H1: µD < 0 c. H0: µnew - µcurrent = 0 H1: µnew - µcurrent < 0 d. H0: µnew - µcurrent = 0 H1: µnew - µcurrent > 0 II. What is the dependent variable in this study?
- a) the null hypothesis for this test would be? b) the alternative hypothesis for this test would be?For c is the null hypothesis rejected?Express the null hypothesis H0 and the alternative hypothesis Ha in notation form in the following scenarios. 1. A random sample of 60 working students was taken in order to determine whether the average age ofworking students is different from 19 years. 2. The number of defective batteries produced by the company is not equal to 12 batteries a day as claimed bythe manager of the company.
