100% Ev Insert Table Chart View Zoom Add Category #6 + Sheet1 #1 #2 #3 #4 #5 A study examined the accuracy of consumer technology used for counting steps. The report states that when a random sample of 28 healthy adults each walked exactly 500 steps on a treadmill, the iphone app reported an average of 541 steps with a standard deviation of 65 steps . By comparison, the same 28 adults also use a Fitbit reported an average of 466 steps with a standard deviation of 90 steps. See the table below for the results you will use for your hypothesis test. Do these results provide significant evidence that the step results of the iphone app differ significantly from the results of the Fitbit watch? Use a confidence level of 95%. Run the same results for a confidence level of 99% (not 95%). Update and input into the area below to show your work.
