Twenty ditterent statistics students are randomly selected. For each of them, their body temperature (C) is measured and their head circumference (cm) is measured. a. Forthis sample of paired data, what does r represent, and what does p represent? b. Without doing any research or calculations, estimate the value of r. c. Does r change it body temperatures are converted to Fahrenheit degrees? a. Choose the correct answer below. 0 A. r is a statistic that represents the value of the linearoorrelation coefcient computed from the paired sample data, and p is a parameter that represents the proportion of the variation in head circumference that can be explained by variation in body temperature. 0 B. r is a statistic that represents the value of the linear correlation coefcient computed from the paired sample data, and p is a parameter that represents the value of the linear correlation coetticient that would be computed by using all of the paired data in the population of all statistics students. 0 C. r is a statistic that represents the proportion ofthe variation in head circumterence that can be explained by variation in body temperature, and p is a parameterthat represents the value at the linear correlation coeicientthat would be computed by using all of the paired data in the population of aii statistim students. 0 D. r is a parameter that represents the value of the linear correlation coetcient that would be computed by using all of the paired data in the population ofail statistics students. and p is a statistic that represents the value ot ie linear correlation coeicient computed from the paired sample data b. Select the correct choice below and ll in the answer box to complete your choice. (Type an integer or a decimal rounded to one decimal place as needed.) O A: The value of r is estimated to be , because it is likely that there is no correlation between body temperature and head circumference O B- The value of r is estimated to be , because it is likely that body temperature and head circumference are strongly negatively correlated. O C. The value ot r is estimated to be , because it is likely that body temperature and head circumference are strongly positiver conelated. c. Choose the correct answer below. 0 A. The value of r changes, because r is aected by converting all values of a variable to a different scale. 0 B. The value 01 I does not change. because r is not affected by the choice ot x or y. 0 C. The value at I does not change. because r is not aected by relationships that are not linear. O D. The value 0t I does not change, because r is not afiected by converting all values of a variable to a different scale
