question 80

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: $\begin{array}{|r|r|r|r|r|r|r|r|r|r|}\hline13&14&5&6&8&10&7&12&15&3\\\hline\end{array}$ 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.
