In a study of speed dating, female subjects were asked to rate the attractiveness oftheir male dates, and a sample of the results is listed below (1= not attractive;10 = extremely attractive). Find the range, variance, and standard deviation for thegiven sample data. Can the results be used to describe the variation amongattractiveness ratings for the population of adult males?51010 5731065 2 176The range of the sample data is(Round to one decimal place as needed.)The standard deviation of the sample data is(Round to one decimal place as needed.)610 6The variance of the sample data is(Round to one decimal place as needed.)3 9 4 89 32 782N ∞Can the results be used to describe the variation among attractiveness ratings for thepopulation of adult males?A. The results can be used to describe the population because the sample israndom.B. Since it is likely that the male subjects volunteered to participate in speeddating, they may not be representative of all adult males. Therefore, the resultscannot be used to describe the population.C. It is unlikely that a random sample of adult males can be representative of alladult males. Therefore, the results cannot be used to describe the population.D. The results cannot be used to describe the population because a smallersample would be needed.

Hint: By simple calculations of mean, then range and easily able to find the var. and std.…
