The manager of 45 sales people examined their monthly expenditures on entertaining clients. He found that the mean amount was 237.50 with a standard deviation of 27.40.
 
  Assuming the data is bell-shaped, would a claim for the amount of 300 be considered unlikely? Why or why not?

Question 2

The standardized normal distribution has a mean = 0 and a standard deviation = 10.
 
  Indicate whether the statement is true or false

Answer to Question 1

We would expect that virtually all of the sales people had expenses within  3 standard deviations of the mean. Although not very likely, it is possible that a sales person will have expenses in the amount of 300. Less than 2.5 of the sales people would have sales expenses of this amount or more.

Answer to Question 2

FALSE
