Step-by-Step Solution:
Step 1 of 3

Confidence Interval  Sample statistic  Usually a point estimate  Used to estimate population parameter  Sample point estimate +/- margin of error Lower endpoint sample point estimate upper endpoint Margin of error Margin of error  Measure of variability associated with point of estimate at desired level of confidence  Small margin of error means higher precision  Higher desired confidence level means a larger margin of error  Lowest value in the computed confidence level =lower endpoint  Highest value in the computed confidence level= higher endpoint Confidence interval for p  Point estimate +/- margin of error Margin of
