A researcher who is studying voting habits chose 650 registered voters at random, shortly after the 2016 presidential election. Of these voters, 74% said they had voted in the election. However, election records show that only 58% of registered voters voted in the election. Which of the following statements is true? Seventy-four percent is a sample and 58% is a population. Seventy-four percent and 58% are both statistics. Seventy-four percent is a statistic and 58% is a parameter. Seventy-four percent is a parameter and 58% is a statistic. Seventy-four percent and 58% are both parameters.

Step-by-step explanation:

A statistic is a percentage of a sample.

A parameter is a percentage of a population.

So 74% is a statistic and 58% is a parameter.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
