The lecture Confidence Intervals for Proportions by David Spade, PhD is from the course Statistics Part 2. It contains the following chapters:
What is not a benefit of using confidence intervals to summarize a population instead of a single value?
Which interpretation of a 95% confidence interval (a,b) for a population proportion centered at the sample proportion (p) is correct?
What is true regarding the margin of error?
What is not a condition that we need in order to use the normal model to construct a confidence interval for a population proportion?
What is true of the oneproportion zinterval?
What is the 95% confidence interval for a population proportion if the sample proportion is 0.2 and standard deviation is 0.1?
What is the margin of error if the confidence interval is 0.5; 0?
