The following values have been obtained for the critical moisture content of sawdust (lb moisture/lb bone-dry solid): 1.1000, 1.0500, 1.0800, 1.1200, 1.0900, 1.1300, 1.1100, 1.0700. Based on these data, your lab partner submits a confidence interval of 1.0779 <><>

(a) What must be the value of z to obtain such an interval?

(b) What percent confidence interval is represented?
