(Give the answer to three decimal places.) mu = 1.993 (b) Use the given data to produce a point estimate of sigma^2, the variance of salt content for frankfurters. (Give the answer to five decimal places.) sigma^2 = (c) Use the given data to produce an estimate of sigma_t the standard deviation of salt content. (Give the answer to four decimal places.) sigma =
