The lecture Confidence Intervals for Proportions by David Spade, PhD is from the course Statistics Part 2. It contains the following chapters:
Which of the following is NOT a benefit of using confidence intervals to summarize a population instead of a single value?
Which of the following is a CORRECT interpretation of a 95% confidence interval (a,b) for a population proportion centered at the sample proportion ˆp ?
Which of the following is TRUE regarding the margin of error?
Which of the following is NOT a condition that we need in order to use the Normal Model to construct a confidence interval for a population proportion?
Which of the following 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?
