Listed below are the 35 members of the Metro Toledo Automobile Dealers Association. We would like to estimate the mean revenue from dealer service departments. The members are identified by numbering them 00 through 34.

Metro Toledo Automobile Dealers Association

a) The mean revenue

= Total Revenue from the dealer service departments/35

b) The sample of five include 27, 23, 32, 11,  and 13

c) Using systematic random sampling, the dealers included in the sample are: 7, 13, 19, 25, and 31.

Step-by-step explanation:

a) The mean value is the total value divided by the number of elements. The mean revenue is, therefore, the total revenue from the dealer service departments divided by the number of dealers.  This gives an average revenue from each dealer, which is a statistic to describe the population.

b) The sample of five cannot include any number that is outside the population.  For example, 85 is not a number allocated to any dealer in the indicated population, therefore, it cannot form part of the population sample.

c) The systematic random sampling starts from 7 and chooses the sixth number after 7.  Therefore, the next four numbers are multiples of 6.  This is why we choose 13, 19, 25, and 31.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
