Answer #1

Solution:

A support group has 14 patients that attend each week. Suppose 3 patients are selected at random to participate in a study. How many different samples of this size can be selected from this population of 14 patients using experimental sampling and theoretical sampling?

a) Experimental sampling:

Numbr of samples possibe=NCn

N=14,n=3

Number of samples possible=14C3=14!/3!12!

=(14 * 13 * 12) / (3 * 2 * 1)

= 364

b)Theoretical sampling:

Number of possible sample=Nn= = 2744

Two hundred students were selected at random from those enrolled at a large college in Alabama. Each student in the sample was asked whether they ate 5 or more apples in a typical week, and their cholesterol levels were also measured. The average cholesterol level was significantly lower for the group who ate 5 or more apples per week than for the group that did not. A. Did the study use a random selection from some population? If yes, what...
