b. Without doing any research or calculations, estimate the value of r. c. Does r change if body temperatures are converted to Fahrenheit degrees? O B. ris 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 p is a statistic that represents the value of the linear correlation coefficient computed from the paired sample data. Oc. ris a statistic that represents the value of the linear correlation coefficient 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. O D. ris a statistic that represents the value of the linear correlation coefficient computed from the paired sample data, and p 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. b. Select the corect choice below and fill 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 ris estimated to be because it is likely that body temperature and head circumference are strongly positively correlated OB. The value of ris estimated to be because it is likely that there is no correlation bebween body temperature and head circumference. O C. The value of r is estimated to be because it is likely that body temperature and head circumference are strongly negatively correlated. c. Choose the correct answer below. OA The value of r does not change, because r is not affected by converting all values of a variable to a different scale. OB. The value of r does not change, because r is not affected by relationships that are not linear. OC. The value of r changes, because r is affected by converting all values of a variable to a different scale. OD. The value of r does not change, because r is not affected by the choice of x or y
