Essay

Consider a set of 50 measurements with mean 50.2 and standard deviation 18.7 and with the following observed frequencies. $$\begin{array} { l c } \text { Interval } & \text { Observed Frequencies } \\39.99 \text { and less } & 12 \\40 - 59.99 & 18 \\60 - 79.99 & 15 \\80 \text {-and higher } & 5\end{array}$$ It is desired to test whether these measurements came from a normal population.
-Calculate the expected frequency for the interval 80 and higher.
