4. Before and after tests are to be made on the breaking strengths (oz) of a certain type of yarn. Specifically, seven determinations of the breaking strength are made on test pieces of the yarn before a spinning machine is reset and five on test pieces after the machine istreset, with the following results: Before: 22.7 25.7 20.7 26.7 21.2 19.2 22.7 After: 23.2 23.7 25.2 23.7 24.7 Assuming that determinations made "after reset" and determinations made "before reset" are independently distributed as N(,of) and N (z, 0), respectively, find a 95% confidence interval for #, -Ha without assuming equal variances.
