1. Which of the following is true about a 90% confidence interval of the mean: a. 90 out of 100 sample means will fall within the limits of the confidence interval. b. 90 out of 100 confidence intervals will contain the population mean. c. 90% of population means will fall within the limits of the confidence interval. d. There is a 0.1 probability that the population mean falls within the limits of the confidence interval.

Step 1: A 90% confidence interval means that if we were to take many samples and calculate a confidence interval for each sample, 90% of those intervals would contain the true population mean. Show more…

Which of the following statements are true about a 95% confidence interval for a certain population mean? About 5 out of 100 intervals constructed like this will miss the actual population mean. The population standard deviation must be provided to construct such an interval. If the sample size is less than 30, then the population does not follow a normal distribution. The probability that this interval contains the actual population mean is 95%. The margin of error becomes smaller if the same sample is used to construct a 90% confidence interval for the same population.

Which of the following statements about confidence intervals do you believe to be true? a. A 95% confidence interval gives the range of values likely to include 95 out of 100 sample data values. b. A confidence interval can be calculated using an estimate of the parameter plus a multiple of the standard deviation. If you want to increase the width of the confidence interval, you should increase the sample size. c. A confidence interval gives an estimated range of values likely to include an unknown population parameter. d. A 95% confidence interval is wider than a 99% confidence interval.
