Show transcribed image text QUESTION 22 Last year it took students and average of 80 minutes to finish the final exam. Suppose the average time a sample of 20 students takes to finish this year's final exam has a mean of 85 minutes and standard deviation of 15. We see that a histogram of the data shows no signs of skewness and a BoxPlot shows no outliers. We want to run a hypothesis test to see if this year's exam is significantly longer than last years. (use a-0.01) What are the correct hypotheses for this test? Ho: Î¼-80 Ha:1# 80 Ho: Î¼-80 Ha: Î¼ 80 Ho: Î¼ 80 Ha: Î¼-80 @
