For a population that has a standard deviation of 12, 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 97 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 _ and _

(write integers or decimals rounded to two decimals places as needed)
