We wish to determine if average run times are changing in the annual Cherry Blossom Run. In 2006, the average run time for this 10-mile event was 93.29 minutes (93 minutes and 17 seconds). The data le CherryBlossomRun2012 contains a random sample of run times in 2012. We wish to test the hypothesis that run times have changed. a) Which of the following is an appropriate set of hypotheses? O Ho: :4 = 93.29; Ha: I4 > 93.29 O HO: ,4 = 93.29; Ha: u 93.29; Ha: I4 = 93.29 0 Hg: :4 = 93.29; Ha: u e 93.29 0 H0: ,4
