The owner of a fitness watch would like to determine if the mean number of steps he takes per day differs from the recommended 10,000 steps per day, using a =0.01. He selects a random sample of 50 days with the intention of
testing the hypotheses How = 10,000 steps versus Hou+ 10,000 steps where = the true mean number of steps
taken per day.
Which of the following values of the alternative hypothesis would yield the greatest power to reject the null
hypothesis?
Ow=9,000
Ow=9,500
O = 10,000
O = 10,500
