He chooses to eliminate the variable $x$ . Which statement correctly describes his process and solution? Nathan multiplies $-2 x+3 y=6$ by 2 and then subtracts the equations. He finds the result is a contradiction, so there is no solution. Nathan multiplies $-2 x+3 y=6$ by 2 and then adds the equations. He finds the result is an identity, so there are infinitely many solutions. Nathan multiplies $-2 x+3 y=6$ by 2 and then adds the equations.

Twenty different statistics students are randomly selected. For each of them, their body temperature $\left({ }^{\circ} \mathrm{C}\right)$ is measured and their head circumference $(\mathrm{cm})$ 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 body temperatures are converted to Fahrenheit degrees? A. $r$ is a statistic that represents the proportion of the variation in head circumference that can be explained by variation in body temperature, and $\rho$ 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. $r$ 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 value of the linear correlation coefficient that would be computed by using all of the paired data in the population of all statistics students. C. $r$ 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 head circumference that can be explained by variation in body temperature. D. $r$ 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. Select the correct 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.) The value of $r$ is estimated to be $\square$ because it is likely that body temperature and head circumference are strongly positively correlated. B.
