Sugar content: A broth used to manufacture a pharmaceutical product has its sugar content, In milligrams per millliter, measured several times on each of three successive days. Can you conclude that the warlability of the process is greater on the third day than on the first day? Let . denote the variability of sugar content on the third day and Up denote the variability of Sugar content on the first day. Use the Q =U.JV level and the critical value methnod with the table.

She measures the time (In minutes) before freeze-up for 0 computers one month after installation and for * computers seven months after installation. The results are shown. Can you conclude that the time to freeze-up differs in variability In the seventh month and the first month after installation? Let 5 denote the variability in time to freeze-up in the first month after Installation. Use the Q = U.10 level and the critical value method with the table. One month: 215.9 2351 225.6 2444 2453 207.4 Seven months: 1273 2013 1742 2462 1494 1564 Sand data to Excoil State the null and alternate hypothesis; V H This is a two-tailed Fart: 1 / 5 Find the critical value.

In a study of birth order and intelligence, 19 tests were given to 18 - and 19-year- old men to estimate the size of the difference, If any, between the mean Iqs of firstborn sons and secondborn sons. The following data for 10 firstborn sons and 10 secondborn sons are consistent with the means and standard deviations reported in the article. Assume that the samples come from normal populations.

Let 5 denote the standard deviation in the 10s of firstbom sons. Use the 0 = 0.03 level, Part 1 of 5 State the null and alternate hypotheses. H :G This hypothesis test is a right-talled test. Fart: 1 / 5 Part 2 of 5 Find the critical value. Round the answer to at least two decimal places. The critical value is J
