- A museum is open to the public for six hours a day from Monday to Friday every week. The number of visitors, \(V\), to the museum on ten randomly chosen days were as follows:
$$\begin{array} { l l l l l l l l l l }
182 & 172 & 113 & 99 & 168 & 183 & 135 & 129 & 150 & 108
\end{array}$$
- Calculate an unbiased estimate of the mean of \(V\).
Assuming that \(V\) is normally distributed with a variance of 130 ,
- find a 95\% confidence interval for the mean of \(V\).
