Suppose that you obtained data by taking a random sample from a population and that you intend to find a confidence interval for the population mean. Answer True or False to the following question. Increasing the confidence level from 95% to 99% will decrease the margin of error.

Step 1
A confidence interval is a range of values that is likely to contain the true population parameter with a certain level of confidence. The margin of error is the amount of error that we allow for in our estimate of the population parameter. Now, let's consider Show more…

True or False: A $95 \%$ confidence interval for a population proportion with lower bound 0.45 and upper bound 0.51 means there is a $95 \%$ probability the population proportion is between 0.45 and 0.51.

Estimating a Population Proportion
For a given confidence level 100(1 - α)% (e.g., when α = 0.05, the confidence level is 95%) and population standard deviation σ, the width of the confidence interval for the population mean is wider, the smaller the sample size n. (True or False) Provide an explanation.
