In an effort to predict customer arrivals better, the Avalon grocery store counted the number of customers who arrived at the store during randomly selected 10-minute intervals. The following table shows these data. For example, there were 12-10minute intervals in which no customers arrived, and 27 10minute intervals in which one customer arrived.
a. Using α = 0.05, perform a chisquare test to determine if the number of customers arriving over a 10minute interval follows the Poisson probability distribution.
b. Determine the pvalue using Excel and interpret its meaning.
