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.

Cris Turlock owns and manages a small business in San Francisco, California. The business provides breakfast and brunch food, via carts parked along sidewalks, to people in the business district of the city. Being an experienced businessperson, Cris provides incentives for the salespeople operating the food carts. This year, she plans to offer monetary bonuses to her salespeople based on their individual mean daily sales. Her first task is to see if there is a significant difference in the mean daily sales among the different salespeople. She chooses a "sample" of days for each salesperson and records the sales for each day. She then runs a one-way, independent-samples ANOVA test to determine whether or not she can conclude that at least one salesperson's performances is significantly different from the others. (Otherwise, she'll split the bonuses evenly among all the salespeople.) In her ANOVA, the "groups" are the different salespeople, and the variable of interest is the daily sales…
