Question 8 of 10, Step 1 of 1 9/19 Correct How will decreasing the level of confidence without changing the sample size affect the width of a confidence interval for a population mean? Assume that the population standard deviation is unknown and the population distribution is approximately normal. Select your answer from the choices below. Answer E Tables Ke Keyboard She The margin of error will increase because the critical value will decrease. The increased margin of error will cause the confidence interval to be wider. O The margin of error will decrease because the critical value will increase. The decreased margin of error will cause the confidence interval to be narrower. O The margin of error will increase because the critical value will increase. The increased margin of error will cause the confidence interval to be wider. O The margin of error will decrease because the critical value will decrease. The decreased margin of will cause the confidence interval to be narrower.
