question 32

Short Answer

A random sample of 10 university students was surveyed to determine the amount of time they spent weekly using a personal computer. The times (in hours) were: $\begin{array}{|l|l|l|l|l|l|l|l|l|l|}\hline13 & 14 & 5 & 6 & 8 & 10 & 7 & 12 & 15 & 3 \\\hline\end{array}$ If the times are normally distributed with a standard deviation of 5.2 hours, estimate with 90% confidence the mean weekly time spent using a personal computer for all university students.
