Twenty different statistics students are randomly selected. For each of them, their body temperature (C) is measured and their head circumference (cm) ismeasured.a. For this 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 if body temperatures are converted to Fahrenheit degrees?a. Choose the correct answer below.*****OA. r is a statistic that represents the value of the linear correlation coefficient computed from the paired sample data, and p is a parameter that represents thevalue of the linear correlation coefficient that would be computed by using all of the paired data in the population of all statistics students.OB. 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 allstatistics students, and p is a statistic that represents the value of the linear correlation coefficient computed from the paired sample data.OC. r is a statistic that represents the proportion of the variation in head circumference that can be explained by variation in body temperature, and p is aparameter 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 statisticsstudents.OD. r is a statistic that represents the value of the linear correlation coefficient computed from the paired sample data, and p is a parameter that represents theproportion of the variation in head circumference that can be explained by variation in body temperature.
