Step-by-step explanation:
The width of a normal confidence interval is given by:
In which z is the critical value according to the confidence level, is the standard deviation of the population and n is the size of the sample.
W and n are inverse proportional, that is, as n(the sample size) increases, W(the width of the interval) decreases, that is, the interval becomes narrower..
So the correct answer is:
d. It would become narrower

Then, x = 4 / 2 = 2;
The equation of the line is x = 2.
