On average, a banana will last 6.5 days from the time it is purchased in the store to the time it is too rotten to eat.  Is the mean time to spoil greater if the banana is hung from the ceiling? The data show results of an experiment with 14 bananas that are hung from the ceiling. Assume that that distribution of the population is normal.

9.1, 9.2, 7.7, 8.8, 9.2, 5.5, 6.4, 7.2, 7.3, 9, 5.2, 8.8, 5.5, 8.3

What can be concluded at the the αα = 0.10 level of significance level of significance?
