LA health specialist wants to determine the average number of hours a person exercises in a day during the quarantine period. She found out that the mean number of hours a person exercises in a day during the quarantine period is 80 minutes. A andom sample of 29 persons were surveyed and found that their mean is 65 minutes nd a standard deviation of 10 minutes. Test the hypothesis at 2% level of significance nd assume that the population is normally distributed.

Question
Determine the given of the problems below and formulate the null and alternative hypotheses both in words and symbols. Write your answer in your notebook. Please foliow the format in the examples. 1A health specialist wants to determine the average number of hours a person exercises in a day during the quarantine period. She found out that the mean number of hours a person exercises in a day during the quarantine period is 80 minutes. A random sample of 29 persons were surveyed and found that their mean is 65 minutes and a standard deviation of 10 minutes. Test the hypothesis at 2% level of significance and assume that the population is normally distributed. 2. A study was conducted to determine the marrying age of teachers. It was found out that the mean marrying age of teachers is 30 years old. Fifteen teachers were surveyed randomly and found that their mean marrying age was 33 years old with a standard deviation of 5 years. Use 10% level of significance to test the hypothesis and assume that the population is normally distributed. 3. An association of City Mayors conducted a study to determine the average number of times a family went to buy necessities in a week. They found that the mean is 4 times in a week. A random sample of 20 families were asked and found a mean of 5 times in a week and a standard deviation of 2. Use 5% significance level to test that the population mean is not equal to 5. Assume that the population is normally distributed.
