Find the range, variance, and standard deviation for the given sample data. Include appropriate units (such as "minutes") in your results. (The same data were used in Section 3-I, where we found measures of center. Here we find measures of variation.) Then answer the given questions. In a study of speed dating conducted at Columbia University, female subjects were asked to rate the attractiveness of their male dates, and a sample of the results is listed below $(1=\text { not attractive; } 10=$ extremely attractive). Can the results be used to describe the variation among attractiveness ratings for the population of adult males? $$\begin{array}{rrrrrrrrrrrrrrrrrrr} 5 & 8 & 3 & 8 & 6 & 10 & 3 & 7 & 9 & 8 & 5 & 5 & 6 & 8 & 8 & 7 & 3 & 5 & 5 & 6 & 8 & 7 & 8 & 8 & 8 & 7 \end{array}$$
