FURTHER APPLICATIONS OF THE RUNS TEST

Referring to Problem 17.3, and assuming a significance level of 0.05, determine whether the sample lifetimes of the batteries produced by the PQR Company are random. Assume the lifetimes of the batteries given in Table 17.3 were recorded in a row by row fashion. That is, the first lifetime was 217, the second lifetime was 230, and so forth until the last lifetime, 268. Work the problem first by hand, supplying all the details of the runs test for randomness. Follow this with the STATISTIX solution to the problem.
