Use the given information to find the number of degrees of freedom, the critical values x and xp, and the confidence interval estimate of o. It is reasonable to assume that a simple random sample has been selected from a population with a normal distribution. - X Platelet Counts of Women 98% confidence; n = 28, s = 65.5.
