Time can be expressed on different levels of scale, including days, weeks, months, and years. Can the scale provide influence perception of time? For example, if you placed an order over the phone, would it make a difference if you were told the package would arrive in four weeks or in one month? To investigate this, two researchers asked a group of 267 college students to imagine that their car needed major repairs and would have to stay at the shop. Depending on the group they were randomized to, the student was either told it would take 1 month or 30/31 days. Each student was then asked to give best- and worst-case estimates of when the car would be ready. The interval between these two estimates (in days) was the response. Here are the results: Group 30/31 days In X 20.4 1 month 24.8 Suppose you want to construct a 95% confidence interval for the difference in populations means. What would be the upper limit of the 95% confidence interval? Use the conservative degrees of freedom here. Type your answer... S 14.3 13.9 177 90
