Question
Recent study stated that if a person chewed gum, the average number of sticks of gum he or she chewed daily was 8. To test the claim, a researcher selected a random sample of 36 gum chewers and found the mean number of sticks of gum chewed per day was 9. The standard deviation of the population is 1.
a- At a = 0.05, is the number of sticks of gum a person chews per day actually greater than 8? Calculate the value of the test statistic and state the hypotheses, and conclusion.
b- What would your conclusion be if the p-value of the test is equal to 0.0?c- State and check the assumptions of the test you used in (a)
