Question Set 3: Confidence Interval

The owner of Scooter Sharing Company wants to estimate the proportion of all spin bikes reservations made by seniors (Upper division students) in the first week of college at Penn State. In a random sample of 45 reservations, 13 were made by seniors.

Question set 3:

Use StatKey(Links to an external site.) to construct a bootstrap sampling distribution for a single proportion given Count = 13 and Sample Size = 45. Include a screenshot of that sampling distribution here. What is the standard error of that distribution?

Question set 3:

Use the general form of a confidence interval to construct a 99% confidence interval to estimate the proportion of all reservations that were made by seniors. Remember always to show all of your work. For a review of this procedure, see page 7.4.2 in the online course notes.
