Question 7

A lakefront resort is planning for its summer busy season. It wishes to estimate with 95% confidence the average number of nights each guest will stay in a consecutive visit. Using a sample of guests who stayed last year, the average number of nights per guest is calculated at 5 nights. The standard deviation of the sample is 1.5 nights. The size of the sample used is 120 guests and the resort desires a precision of plus or minus .5 nights. Within what range below can the resort expect with 95% confidence for the true population mean to fall?

3.12 to 6.88

3.35 to 6.65

2.42 to 7.58

4.10 to 5.50

4.65 to 6.65

Question 8

Consider the following hypothesis: there is no relationship between income and amount of money spent on food. If the hypothesis presented is tested using a .05 alpha level and the resulting p value is .01, which of the following interpretations of the results is most appropriate?

There is no relationship between income and food expenditures

There is a relationship between income and food expenditures

As income increases, food expenditures increase

As income decreases, the percentage of income spent on food increases

None of the above
