We wish to test the hypotheses Ho: P1-P2 = 0 versus the hypothesis H1: p1 - p2 O at a 5% level of significance. Here, p1 denotes, of all bolts manufactured on Machine A, that fraction that are defective, and p2 denotes, of all bolts manufactured on Machine B, that fraction which consists of defective bolts. In order to test theses hypotheses, we obtain a random sample of 400 bolts manufactured on Machine A, and independently, we obtain a random sample 400 bolts from Machine B. Of the bolts from the Machine A sample we find that 20 are defective, whereas for the Machine B sample we find that 30 are defective. Compute the p-value.

A grinding machine will be qualified for a particular task if less than or equal to 8% of the parts that it produces are defectie. We coect soe samples to determine if the machine be qualified for the task. How can we state the null hypothesis and alternative hypothesis?

4. In one of Mendel’s early genetics experiments, he observed two traits on each of 556 garden peas: shape (Round or Angular) and Colour (Yellow or Green). The results are listed in dataset “Mendel”. According to his model, the four classes should occur in a 9:3:3:1 ratio. Do the data support that presumption? Do a relevant hypothesis test at the alpha of 0.05 level of significance. 4.1.

5. A researcher wanted to know if individuals have better reaction times depending on when the test is taken -- in the morning or in the afternoon. He randomly assigned 16 participants to take the same reaction time test in either the morning or the afternoon. The following results were obtained, where lower scores indicate faster reaction time. Assume that the parametric test assumptions ARE violated. Conduct an appropriate statistical test using an alpha of .05 and the eight steps of hypothesis testing.

1.) Several companies have been developing electronic guidance systems for cars. Motorola and Germany's Blaupunkt are two firms at the forefront of such research. Out of 120 trials of the Motorola model, 101 were successful; and out of 200 tests of the Blaupunkt model, 110 were successful. Is there evidence to conclude that the Motorola electronic guidance system is superior to the German competitor? State the null and alternative hypothesis. Test the hypothesis with significance level of 5%. State your conclusion. 2.)

3.) In a particular epidemic disease, 400 individuals were surveyed by a well-established pharmaceutical company to determine if the company’s new vaccine was effective after 4 months. Among the 120 individuals who had that disease and were given the shot, 29 were cured and achieved immunity after 4 months. Among 280 individuals who had the disease but were not given the shot, 56 were cured and achieved immunity after 4 months. Is there enough statistical evidence to support the company’s claim of the effectiveness of the vaccine?
