Question

Consider the following results for independent samples taken from two populations.

Sample 1 Sample 2
n1 = 400 n2 = 300
p 1 = .48 p 2 = .36

What is the point estimate of the difference between the two population proportions (to 2 decimals)?

Answer 1

The point estimate of the difference between the two population proportions is 0.12.

Step-by-step explanation:

The point estimate of the difference between the two population proportions can be calculated by subtracting the sample proportions. The point estimate is given by p1 - p2, where p1 is the sample proportion of Sample 1 and p2 is the sample proportion of Sample 2.

In this case, the point estimate is 0.48 - 0.36 = 0.12.

The point estimate of the difference between the two population proportions is 0.12.
