Answer:And for this case the margin of error would be:

If the level of confidence increase we can conclude that the value of would increase and the the confidence interval would be wider, since the margin of error increase.

c. Increase; wider

Step-by-step explanation:Previous concepts

A

confidence intervalis “a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval”.The

margin of erroris the range of values below and above the sample statistic in a confidence interval.Normal distribution, is a “probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean”.Solution to the problemLet’s assume that we have a parameter of interest and we want to estimate the value of p with and in general the confidence interval if the distribution of p is normal is given by:

And for this case the margin of error would be:

If the level of confidence increase we can conclude that the value of would increase and the the confidence interval would be wider, since the margin of error increase.
