Question
The article "Sensory and Mechanical Assessment of the Quality of Frankfurters" reported the following salt content (percentage by weight) for 10 frankfurters. 2.32 2.17 1.70 1.23 1.70 2.42 1.76 2.16 2.25 2.46 (a) Use the given data to produce a point estimate of , the true mean salt content for frankfurters. (Give the answer to three decimal places.) = (b) Use the given data to produce a point estimate of 2, the variance of salt content for frankfurters. (Give the answer to five decimal places.) 2 = (c) Use the given data to produce an estimate of , the standard deviation of salt content. (Give the answer to four decimal places.) = You may need to use the appropriate table in Appendix A to answer this question.
