Suppose the mean of a population is μ = 36. A researcher (who does not know that μ = 36) selects a random sample of size n from this population. Then he constructs a 90% confidence interval of the population mean. The true population mean and the researcher's 90% confidence interval of the population mean are shown in the following graph. Use the graph to answer the questions that follow. True Population Mean 90% Confidence Interval of the Population Mean 34 35 36 37 38 39 40 41 42 43 44 Sample Mean In this case, tsM = (?) Use the grey star to mark the mean of the sample. (Be sure to place the star on the horizontal blue line segment that represents the confidence interval.) To construct the confidence interval, the quantity tsM is subtracted from and added to the sample mean. Suppose that the researcher uses the same sample but decides to construct a 80% confidence interval of the mean of the population. Compared with the center of the 90% confidence interval, the center of the 80% confidence interval Compared to the 90% confidence interval, the 80% confidence interval At the same confidence level, in the sample size would have a similar effect on the width of the confidence interval as changing the confidence level from 90% to 80%.
