80. Creek Ratz is a very popular restaurant located along the coast of northern Florida. They serve a variety of steak and seafood dinners. During the summer beach season, they do not take reservations or accept “call ahead” seating. Management of the restaurant is concerned with the time a patron must wait before being seated for dinner. Listed below is the wait time, in minutes, for the 25 tables seated last Saturday night.

28 39 23 67 37 28 56 40 28 50

51 45 44 65 61 27 24 61 34 44

64 25 24 27 29

a. Explain why the times are a population.

The times are considered a population, because they encompass all of the seating times from that Saturday night; anything less than all would be a sampling.

b. Find the mean and median of the times.

Mean = 40.84; Median = 39

c. Find the range and the standard deviation of the times.

Range = 44; Standard deviation = 14.85

82. The following frequency distribution reports the electricity cost for a sample of 50 two-bedroom apartments in Albuquerque, New Mexico during the month of May last year.

Electricity Cost Frequency

$80 up to $100 3 100 up to 120 8 120 up to 140 12 140 up to 160 16 160 up to 180 7 180 up to 200 4 Total 50

a. Estimate the mean cost.

Mean = falls within the $140 to $160; if using middle value for all costs (i.e. $90 for 1st category, $110 for 2nd, etc…) mean cost is $141.20.

b. Estimate the standard deviation.

Standard deviation = 26.24

c. Use the Empirical Rule to estimate the proportion of costs within two standard deviations of the mean. What are these limits?

Mean – 2s = 88.73

Mean + 2s = 193.67

87. Refer to the Real Estate data, which reports information on homes sold in the Denver, Colorado, area last year.
