A coffee machine sales representative visits 5 businesses per day. A sample of 200 days gives the frequencies of coffee machine 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.
Should the assumption of a binomial distribution be rejected at the 1% significance level?
