Are random arrivals at a shoe store at the local mall Poisson distributed? Suppose a mall employee researches this question by gathering data for arrivals during one-minute intervals on a weekday between 6:30 P.M. and 8:00 P.M. The data obtained follow. Use a = .05 to determine whether the observed data seem to be from a Poisson distribution. Arrivals per Minute 0 1 2 3 4 5 26 Observed Frequency 26 40 53 36 17 12 8
(Round the value of A to 1 decimal place, e.g. 25.7. Round the intermediate values and final answer to 2 decimal places, e.g. 25.78.) Observed X²= There is eText enough not enough evidence to reject the claim that the observed frequency of arrivals is Poisson distributed. a
