Which of the following statements regarding confidence intervals is FALSE? O A. The size of a confidence interval (i.e., how wide or narrow) is determined by the sample standard deviation, the sample size, and the associated z-score at the 95% confidence level. O B. A confidence interval is a range of scores believed with some level of confidence to contain the true population mean. O C. A confidence interval uses the sample mean as a central point and then adds and subtracts the margin of error to the sample mean to obtain a lower limit value and an upper limit value. O D. A 99% confidence interval will have a wider range of values compared to a 95% confidence interval. QUESTION 11 Whenever we convert scores from their original units of measurement (e.g., minutes, MPH, ounces) into z-scores, the mean will always convert to a z-score equal to and the standard deviation will convert to a z-score of O A. 1;0 O B. 0;0 O C.0;1 O D.1;1 QUESTION 12 What factors affect how well a sample mean estimates a population mean? O A. The scale of measurement (N.O.I.R.) and the method used to randomly assign subjects to levels of the independent variable. O B. Sample size and sampling method used to select subjects from the population. O C. The size of the sample standard deviation and how wide or narrow the histogram for the data is. O D.
