i need assistance on this question,please

There are three factors that affect the width of a large-sample confidence

interval for p: the confidence interval, the sample size, and the sample proportion,

^p. In each of the following problems, determine whether the width of the

resulting confidence interval for p increases or decreases.

a. Confidence level and ^p are constant, and n increases.

b. Sample size and ^p are constant, and confidence level decreases.

c. Sample size and confidence level are constant, and ^p(>0.5) increases.
