mean
In order to control costs, a company wishes to study the amount of money its sales force spends entertaining clients. The following is a random sample of six
entertainment expenses (dinner costs for four people) from expense reports submitted by members of the sales force.
$357 $332 $309 $345 $325 $339
334.50

334.50
Enter tolerance intervals
1) Calculatex", s^2, and s for the expense data.
2) Assuming that the distribution of entertainment expenses is approximately normally distributed, calculate estimates of tolerance intervals containing 68.26 percent,
95.44 percent, and 99.73 percent of all entertainment expenses by the sales force.
3) If a member of the sales force submits an entertainment expense (dinner cost for four) of $390, should this expense be considered unusually high (and possibly
worthy of investigation by the company)? Explain your answer.

Consider the data ("Value") in column A.
TASK: Create a histogram for the data.
You will need to find (calculate):
- Frequency of bins (use the FREQUENCY formula)
- The number of classes (apply the 2^k formula via the "Numer of Classes" cell (G2))
- Maximum and Minimum values
- Number of data
You will need to create (calculate):
- Class boundaries
- Frequency of upper Class Boundaries (use the FREQUENCY formula)
- Class midpoints
- Relative frequency
- Cumulative frequencies
