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. The Q-Q plot for the sales (y) is shown in Figure 10.12000100008000600040002000Day123456789101112131415-2OTable 10Number of cakes produced (x)901913916917919920922924-1.5929931932933936940946Figure 10: Q-Q Plot for sales (v)Q-Q Plot for y-1-0.5Normal Line0Normal Quantiles0.5Sales ($) (v)375041504950O54005500600061006800725073507950840087509050101501Mu=6770, Sigma=1870.61.52
