Question

We wish to determine the proportion of small- to medium-sized streams in eastern North Carolina which have runoff from hog farms in order to prepare for issues arising from water quality in the aftermath of hurricanes. A random sample of 174 small- to medium-sized streams is selected and it is found that 100 of them have runoff from hog farms. Which of the following is the value of the parameter of interest in this setting?

a. 0.02322.
b. 0.240.
c. 0.760.
d. the value of the parameter of interest cannot be determined from the given information.

Answer 1

The value of the parameter of interest in this setting is 0.5747.

Explanation:

The parameter of interest is:

The proportion of small- to medium-sized streams in eastern North Carolina which have runoff from hog farms in order to prepare for issues arising from water quality in the aftermath of hurricanes.

A random sample of 174 small- to medium-sized streams is selected and it is found that 100 of them have runoff from hog farms.

This means that the value of the parameter of interest is:

`p = (100)/(174) = 0.5747`

The value of the parameter of interest in this setting is 0.5747.
