Twenty different statistics students are randomly selected. For each of them, their body temperature (degreesC) is measured and their head circumference (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?

See the explanation below.

Step-by-step explanation:

a. For this sample of paired data, what does r represent, and what does rho represent?

r stands for the correlation coefficient value that is normally estimated by pairing the sample data.

rho refers to parameter that  is employed to denote the linear correlation coefficient value that is intended to be calculated by employing the every paired data in the population of all statistics students.

b. Without doing any research or calculations, estimate the value of r.

The computed value of r is 0.

The reason is that it is possible that no correlation exist between body temperature and head circumference.

c. Does r change if body temperatures are converted to Fahrenheit degrees?

This will make the value of r to change.

The reason is that when the all values of a variable is changed to another scale, it will have any influence on the value of r.

the y will be in still but your answer will be y x 3
