Subject:StatisticsPrice: Bought3

The margin of error in estimating the population mean of a normal population is E = 9.3 when the sample size is 15. If the sample size had been 18 and the sample standard deviation did not change, would the margin of error be larger or smaller than 9.3? Explain your answer.A. Smaller. E decreases as the square root of the sample size gets larger.B. Smaller. E increases as the square root of the sample size gets larger.C. Larger. E decreases as the square root of the sample size gets larger.D. Larger. E increases as the square root of the sample size gets larger.
