If all other quantities remain the same, how does the indicated change affect the width of a confidence interval? Decrease the confidence level from 99% to 95%:
A. The interval will get wider
B. The interval will get narrower
C. The interval will stay the same
Homework Answers
If the confidence interval is more, then the width of the interval will be large whereas if the confidence interval is less, then the width is less.
The width increases as the confidence level increases
If it is decreased from 99 to 95 percent, the interval will get narrower.
Option B is the right answer.

Which one is the right one?
Keeping all the other things the same, if there is an increase in the sample size the confidence interval would become O No change Wider 0 Change from a 99% to a 95% level of confidence Narrower

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...

Use the sample information x¯ = 43, σ = 3, n = 13 to calculate the following confidence intervals for μ assuming the sample is from a normal population. (a) 90 percent confidence. (Round your answers to 4 decimal places.) The 90% confidence interval is from to (b) 95 percent confidence. (Round your answers to 4 decimal places.) The 95% confidence interval is from to (c) 99 percent confidence. (Round your answers to 4 decimal places.) The 99% confidence interval...

We have sampled n observations from a normal distribution with known standard deviation σ, and constructed a 95% confidence interval for μ. If the confidence level is changed to 99%, which of the following choices is correct? Group of answer choices The confidence interval will become wider. The confidence interval will become narrower. The confidence interval will stay the same. In a particular case, any of these choices may be correct.
