Statistics Problems
Use the above data collected for the below questions.
1) Conduct a hypothesis test analysis to determine if there is a statistical difference between the ages of the sexes in the group. State what you are testing. Write the hypotheses. Show the relevant numbers. Then explain your results. Use alpha = .05.
2) This week you will analyze if women drink more sodas than men. For the purposes of this question, assume that in the past there has been no difference. However, you have seen lots of women drinking sodas the past few months. You will perform a hypothesis test to determine if women now drink more sodas than men. State what you are testing. Write the hypotheses. Show the relevant numbers. Then explain your results. Use alpha = .05.
