The researcher recorded the amount of time each bird spent in the plain chamber during a 60-minute session. Suppose the study produced a mean of M = 56.61 minutes on the plain chamber with SS = 3752 for a sample of n = 14 birds. Construct the 90% confidence interval to estimate the mean amount of time spent on the plain side for the population of birds. Type only the upper interval by using
