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.
