Test whether the number of cakes produced has any effect on sales based on the F-test at the5% level of significance. State the hypotheses, decision rule and conclusion.(d) By considering the Q-Q plot in Figure 10, what can you conclude?(c) A cake shop produces different kinds of cakes a day. The number of cakes produced (x) isthroughout to be linearly related to the sales (y) amount of that particular day. The data werecollected on 15 successive days in Table 10.

In a fishing lodge brochure, the lodge advertises that 75% of its guests catch northern pike over 20 pounds. Suppose that last summer 71 out of a random sample of 86 guests did, in fact, catch northern pike weighing over 20 pounds. Does this indicate that the population proportion of guests who catch pike over 20 pounds is different from 75% (either higher or lower)? Use ? = 0.05. (a) What is the level of significance?

Español A decade-old study found that the proportion, p, of high school seniors who believed that "getting rich" was an important personal goal was 80%. A researcher decides to test whether or not that percentage still stands. He finds that, among the 240 high school seniors in his random sample, 185 believe that "getting rich" is an important goal. Can he conclude, at the 0.10 level of significance, that the proportion has indeed changed? Perform a two-tailed test. Then complete the parts below.
