Transcribed Image Text:A shoe company wants to determine if the new
tread on its top line of running shoes lasts longer
than the original tread. The company recruits 50
runners for a study. Each runner will perform their
typical workout wearing one shoe with the original
tread on one foot and another shoe with the new
tread on the other foot. The foot that wears the new
type of tread will be decided by flipping a coin. After
one month, the runner will wear the new type of
tread on the opposite foot. At the end of the second
month, the difference in tread wear (New - Original)
will be calculated.
What type of sampling is described in this study?
What is the appropriate inference procedure?
one-sample t-test for μ
one-sample z-test for p
