The school board of a large school district would like to raise taxes in the district to pay for new computers. To see if there

is support for a tax increase, they send a survey home with a random sample of students in the district. If the survey is not completed, calls are made to ensure responses are obtained from the parents of every selected student. The survey asks, "Would you be in favor of a modest tax increase to fund the purchase of new computers for all students?” The confidence interval for the true proportion of families that are in favor of a tax increase is 0.70 to 0.80. Members of the community who do not have children in the district complain about not being included in this study. Which of the following sources of bias affected the confidence interval, but is not included among the sources covered by the margin of error?

The source of bias that affected the confidence interval, but is not included among the sources covered by the margin of error is; Under coverage Bias

<h3>How to Identify the source of Bias?</h3>

The source of bias that affected the confidence interval, but is not included among the sources covered by the margin of error is; Under coverage Bias

The reason why I picked under coverage bias is because we see from the survey that they send a survey home with a random sample of students in the district. However, when the survey was not completed, calls are made to ensure responses are obtained from the parents of every selected student. Then the question is changed again.

Thus, it is clear that not all was captured and that is why we go with under coverage bias.

A) exponential is the right answer.

Step-by-step explanation:

The formula used for increase after same number of time is:

A_t = A_0(1+r)^t\\Here\\A_0\ is\ the\ initial amount\\r\ is\ the\ rate\\and\\t\ is\ time

We are given

A_0 = 35000

r = 3%

A_t = 35000(1+0.03)^t\\A_t = 35000(1.03)^t

The function is an exponential function is the value of t can be put equal to 1,2,3,4..... which will increase the final output exponentially

Hence,

A) exponential is the right answer.
