Geoff Brown is the manager for a telemarketing firm and is evaluating the sales rate of experienced workers in order to set minimum standards for new hires. During the past few weeks, he has recorded the number of successful calls per hour for the staff. These data appear next along with some summary statistics he worked out with a statistical software package. Geoff has been a student at the local community college and has heard of many different kinds of probability distributions (binomial, normal, hypergeometric, Poisson, etc.). Could you give Geoff some advice on which distribution to use to fit these data as well as possible and how to decide when a probationary employee should be accepted as having reached full production status? This is important because it means a pay raise for the employee, and there have been some probationary employees in the past who have quit because of discouragement that they would never meet the standard. Successful sales calls per hour during the week of August 14:
4 2 3 1 4 5 5 2 3 2 2 4 5 2 5 3 3 0 1 3 2 8 4 5 2 2 4 1 5 5 4 5 1 2 4
Descriptive statistics:
N: 35 MEAN: 3.229 MEDIAN: 3.000 STANDARD DEVIATION:
1.682 MIN: 0.0 MAX: 8.0 1ST QUARTILE: 2.0 3RD QUARTILE:
5.0
Analyze the distribution of sales calls. Which distribution do you
think Geoff should use for his analysis? Support your
recommendation with your analysis. What standard should be used to
determine if an employee has reached “full production” status?
Explain your recommendation.

A sales manager has sampled past sales records to determine how many refrigerators are sold each day. Daily records for a sample of 10 days have been selected. The sales on these days are: 0, 4, 4, 2, 1, 3, 4, 5, 2, 7. The mean daily sales is ? . The median is .? The variance is ? . The standard deviation is ? . (round to two decimal points)
A telemarketing firm has studied the effects of two factors on the response to its television advertisements. The first factor is the time of day at which the ad is run, while the second is the position of the ad within the hour. The data in the following table, which were obtained by using a completely randomized experimental design, give the number of calls placed to an 800 number following a sample broadcast of the advertisement. If we use Excel...

A government-sponsored telephone counseling service for adolescents tested whether the length of calls would be affected by a special telephone system that had a better sound quality. Over the past several years, the lengths of phone calls (in minutes) were normally distributed with Population Mean = 18 and Population Standard Deviation = 8. They arranged to have the special phone system loaned to them for a day. On that day, the mean length of the 46 calls they received was...
