A Salesperson Makes Five Calls Per Day Assume That the Population Is Binomially Distributed with a Probability

Essay

A salesperson makes five calls per day. A sample of 200 days gives the frequencies of sales volumes listed below: $$\begin{array} { | c | c | } \hline \text { Number of sales } & \text { Observed frequency (days) } \\\hline 0 & 10 \\\hline 1 & 38 \\\hline 2 & 69 \\\hline 3 & 63 \\\hline 4 & 18 \\\hline 5 & 2 \\\hline\end{array}$$ Assume that the population is binomially distributed with a probability of purchase p = 0.50.
Compute the expected frequencies for x = 0, 1, 2, 3, 4 and 5 by using the binomial probability function or the binomial tables. Combine categories if necessary to satisfy the rule of five.
