Sixty statistics students are randomly selected. For each of them, the time of day they filled out the survey and number of family members is measured. a. For this sample of paired data, what does r represent, and what does rho represent? b. Without doing any research or calculations, estimate the value of r. c. Does r change if time of day is converted to minutes rather than hours? Question content area bottom Part 1 a. Choose the correct answer below. A. r is a parameter that represents the value of the linear correlation coefficient that would be computed by using all of the paired data in the population of all statistics students, and rho is a statistic that represents the value of the linear correlation coefficient computed from the paired sample data. B. r is a statistic that represents the value of the linear correlation coefficient computed from the paired sample data, and rho is a parameter that represents the proportion of the variation in number of family members that can be explained by variation in the time of day they filled out the survey. C. r is a statistic that represents the value of the linear correlation coefficient
