Number of Sales
a Salesperson Makes Five Calls Per Day

Number of sales
A salesperson makes five calls per day.A sample of 200 days gives the frequencies of sales volumes listed below $$\begin{array} { | c c | } \hline \begin{array} { c } \text { Number of } \\\text { Sales }\end{array} & \begin{array} { c } \text { Observed } \\\text { Frequency (days) }\end{array} \\\hline 0 & 10 \\1 & 38 \\2 & 69 \\3 & 63 \\4 & 18 \\5 & 2 \\\hline\end{array}$$
-Assume the population is a binomial distribution with a probability of purchase $\pi$
equal to 0.50.Compute the expected frequencies (E_j)for the number of sales by using the binomial tables.Combine if necessary to satisfy the rules of five.
