If all other quantities remain the same, how does the indicated change affect the width of a confidence interval? Decrease the sample size from 120 to 90:
Homework Answers
Margin of error is inversely proportional to the sample size( square root of sample size)
As we increase the sample size ,the margin of error decreases & vice versa.
i.e if you decrease your sample size from 120 to 90 ,the margin of error increases,
So
New margin of error = (√120/√90)×old margin of error

If all other quantities remain the same, how does the indicated change affect the width of a confidence interval? Decrease the sample size from 120 to 90: A. The interval will stay the same B. The interval will get wider C. The interval will get narrower D. Sample size does not have any influence on confidence interval

How will increasing the sample size without changing the level of confidence 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. The margin of error will increase because the critical value will increase and the sample size, n, is located in the denominator of the formula for margin of error. The increased margin of error will...

Which of the following does NOT correctly describe how the width of a confidence interval for a population mean changes when the population standard deviation is known? The interval changes if the sample size decreases. The interval changes if the sample size increases. The interval narrows if the sample size increases and confidence level stays the same. The interval widens if the sample size decreases and the confidence level stays the same. The interval widens if the sample size stays...

Which of the following correctly describes how the width of a confidence interval for a population mean changes when the population standard deviation is known? There is no change if just the sample size increases. The interval widens if the sample size stays the same and confidence level decreases.
