a For a population that has a standard deviation of 26, figure the 95% confidence interval (that is, the lower and upper confidence limits) for parts (a) through (d). Assume that in each case the researcher's sample has a mean of 102 and that the population of individuals is known to follow a normal curve. (a) Figure the 95% confidence interval for samples of size 2. One can be 95% confident that the true population mean is between 65.97 and 138.03. (Type integers or decimals rounded to two decimal places as needed.) (b) Figure the 95% confidence interval for samples of size 3. One can be 95% confident that the true population mean is between and (Type integers or decimals rounded to two decimal places as needed.)
