The Hypothesis Test for One Mean

5) Using the proper symbols, write the null and alternative hypotheses for each scenario below. (2 points each)

a) In 1920, the average age men got married for the first time was 24.6 years. It is believed that young people are waiting longer to get married. A recent study of 120 men found that the average age the men got married for the first time was 29.5 years with a standard deviation of 5.2 years. Is this evidence that the average age men get married has increased?

b) A diet guide says that you will get an average of 140 calories from a serving of vanilla yogurt. Consumer Reports tested 14 brands of vanilla yogurt and found the mean to be 145 with a standard deviation of 5.45. Is this evidence that what the diet guide claims is different from what the researchers found?
