The margin of error in estimating the population mean of a normal population isE= 9.3 when the sample size is 15. If the sample size had been 25 and the sample standard deviation didn't change, would the margin of error be larger or smaller than 9.3?

Question 13 options:

a)

Smaller.Eincreases as the square root of the sample size gets larger.

b)

Smaller.Edecreases as the square root of the sample size gets larger.

c)

Larger.Edecreases as the square root of the sample size gets larger.

d)

Larger.Eincreases as the square root of the sample size gets larger.
