Estimation questions require knowledge of the following topics: estimation of population parameters and margin of error, properties of point estimators, including unbiasedness and variability, logic of confidence intervals, meaning of confidence level and properties of confidence intervals, large sample confidence interval for a difference between two proportions, confidence interval for the slope of a least-squares regression line.
Examples of multiple choice questions with point estimators and confidence intervals:1. The quality department of an electronics manufacturer randomly selected 100 resistors. The mean resistance of the resistors was 201.5Ω and the standard deviation was .4Ω. Find the 98% confidence interval for this problem.
