the population?

A research group is on a college campus and is conducting a survey regarding the coffee consumption of college students in America.The techniques that would probably produce a sample that is most representative of  population is Survey a randomly selected group of students from all- campus event.

Explanation:

While surveying the coffee consumption of college students the group will select the random samples. The Random sample is one which is selected without any kind of partiality. Every student in a survey will get an equal opportunity for selection.

The sample selected by this technique is more reliable as it actually represents the population from which it is taken. This technique can be used only when the size of the population is not very large.

The probability that a person with restless leg syndrome has fibromyalgia is 0.1833.

Step-by-step explanation:

Denote the events as follows:

F = a person with fibromyalgia

R = a person having restless leg syndrome

The information provided is as follows:

P (R | F) = 0.33

P (R | F') = 0.03

P (F) = 0.02

Consider the tree diagram attached below.

Compute the probability that a person with restless leg syndrome has fibromyalgia as follows:

Thus, the probability that a person with restless leg syndrome has fibromyalgia is 0.1833.
