Doctors are interested in determining if men prefer colder temperatures than women. Thirty women and thirty men were asked to state their ideal room temperature. What type of test would they conduct to test this claim?
a. Comparing proportions of dependent samples.
b. One proportion
c. Comparing means of 2 independent samples
d. One mean
e. Comparing two independent proportions
f. Comparing means of dependent samples

The doctors want to test if men prefer colder temperatures than the woman. For these two random samples were taken, one of 30 women and the second of 30 men. The temperature is a continuous variable, it is very difficult to reduce it to two categories "cold" or "hot" because depending on the person, you can feel it in one way or another or there is even another possible category that we could call "temperate" with which the Population proportions would not be the best parameter to study this variable.

On the other hand, the population mean is a better and more illustrative parameter to study this variable, since it is a measure of central tendency, easily summarizes the possible values that the variable can take and it can be studied in both populations.

With all this in mind, the best test to choose to compare the preferred temperature of men and women is a test for population means of independent samples.

I hope you have a SUPER day!
