3 1 Point Which of the following is the correct interpretation of a 95% confidence level? O The confidence level states the probability that a computed confidence interval contains the true population parameter. O If we take repeated random samples of size n and computed a 95% confidence interval for each random sample, 95% of the samples will have a Cl that contains the true population parameter. Save Answer Q4 1 Point Which of the following actions have no impact on the margin of error for a confidence interval for the population mean? O Increase the sample mean Increase the sample size O Increase the standard deviation of the variable X O Increase the confidence level Save Answer Q5 1 Point Refer to the LTDR example in the lecture slides. Suppose that the sample mean and standard deviation remains the same. What is the 95% Cl if the sample size was 25 instead of 110? O (52.6, 100.9) O (71.9, 81.5) O (74.4, 79.0) O (75.7, 77.7)
