A caterer proposes to serve four main courses. For planning purposes, the caterer expects that the proportions of each that will be selected by customers will be: $$\begin{array} { | l | c | }
\hline \text { Selection } & \text { Proportion } \
\hline \text { Roast beef } & 0.50 \
\hline \text { Chicken } & 0.20 \
\hline \text { Fish } & 0.10 \
\hline \text { Vegeterian } & 0.20 \
\hline
\end{array}$$ Of the first 100 customers, 44 select roast beef, 24 select chicken, 13 select fish, and 19 select the vegetarian meal. Should the caterer revise the estimates? Use $\alpha$ = 0.05.
