Rebecca collected data from a random sample of 1200 homeowners in her state asking whether or not they use electric heat. based on the results, she reports that 50% of the homeowners in the nation use electric heat. why is this statistic misleading? a. the sample size is insufficient. b. the statistic contains a calculation error. c. the sample is biased. d. the data contains an outlier.

Hi,

The answer is c. The sample is biased.

This is because the sample is taken on a single state, an Rebecca reports a statistic about the nation. Her data contains information only of her state. If she lives in a very cold state, there is probably more homeowners using electric heat than in a hot state.

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

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.
