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 Observed per Minute Frequency 0 26 1 40 2345 60 29 17 12 6 8 Appendix A Statistical Tables (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 x= There is evidence to reject the claim that the observed frequency of arrivals is Poisson distributed.
