As part of a project targeted at improving the services of a local bakery, a management consultant monitored customer arrivals for several Saturdays and Sundays. Using the arrival data, she estimated the average number of customers arrivals per 10-minute period on Saturdays to be 6.2. She assumed that arrivals per 10-minute interval followed the Poisson distribution shown in the table.
x 0 1 2 3 4 5 6 7 8 9 10 11 12 13
p(x) .002 .013 - .081 .125 .155 - .142 .110 .076 - .026 .014 .007
(a) Compute the missing probabilities.
(b) Plot the distribution.
(c) Find mean (mu) and standard deviation (σ) and plot the intervals (μ) +/- (σ), (μ) +/- 2(σ), and (μ) +/- 3(σ) on your plot of part (b).
(d) The owner of the bakery claims that more than 75 customers per hour enter the store on saturdays. Based on the consultant's data, is this likely? Explain.

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
