Essay

Perform the required correlation test for normality.
-At one bank, twelve customers were selected at random as they entered the bank and asked to record how long they spent waiting in line. The times (in minutes)were as follows.
$\begin{array} { l l l l l l } 6.9 & 3.0 & 5.1 & 1.5 & 2.7 & 7.0 \end{array}$ $\begin{array} { l l l l l l } 6.8 & 2.4 & 6.2 & 1.2 & 3.8 & 4.2 \end{array}$
At the 5% significance level, do the data provide sufficient evidence to conclude that waiting times of customers at this bank are not normally distributed?
