Question 4 A company produces a range of devices for the mobile phone market. Its acceptance policy is that batches with more than 4% defective are returned to the supplier. A random sample of 150 plastic connectors reveals that 8 are defective. 95% Cl for the proportion defective, using one sample p, is (0.023304, 0.102382) What action should you take? O Accept the batch. Reject the batch. Wait and re-do the statistical test, the wrong statistical test was used.
Question 6 > Hypotheses and Conclusions: According to the Centers of Disease Control, about 20% of American young people between the ages of 12 and 19 are obese. A student claims that the students in his local schools are in better shape than the national average, so their proportion of obese students is less than 20%. a) Which are the appropriate null and alternative hypotheses for this study? O Ho: p = 20% HA: P = 20% O Ho: p = 20% HA: P 20% O Ho: P = 0 HA: P = 0 b)Suppose that the result of the statistical test is to Reject Ho. Which is the proper conclusion? O There is not sufficient evidence to support the claim that the students at his local schools have a smaller proportion of obese students. O There is sufficient evidence to support the claim that the students at his local schools have a smaller proportion of obese students. O There is not enough information to answer this question. O The test has proved that the students at his local schools have a smaller proportion of obese…
Question 2 The city of Chicago decides to understand whether its citizens consume more alcohol during the summer period. As a baseline, the average person consumes 0.7L of alcoholic beverages in each week outside the summertime. In June of a given year, they collected a simple random survey of 28 people and estimated an average per capita consumption of 0.95L per week. Moreover, they estimated a sample variance of 0.85L² a) State the null and alternative hypothesis of the test. b) Compute the relevant test statistic. Show all steps. c) The researchers conducting this assessment decide to restrict the type 1 error to 10%. Find the critical value(s) for the test and justify your answer. d) Find the p-value for the test. Explain your answer. Draw a graph with a representation of the p-value with the relevant values in the test. e) Conclude the test.

Question 39 1 In a one-way ANOVA, if the computed F value exceeds the critical F value, what decision is made regarding the null hypothesis? O Reject Ho since there is evidence of a treatment effect. O Do not reject Ho since there is no evidence of a difference. O Do not reject Ho because a mistake has been made. O Reject Ho since there is evidence that all means differ.
Question 16 Match the p-values with the appropriate conclusion: I. 0.00001 II. 0.0297 III. 0.0721 IV. 0.4490(a) The evidence against the null hypothesis is significant, but only at the 10% level. (b) The evidence against the null and in favor of the alternative is very strong. (c) There is not enough evidence to reject the null hypothesis, even at the 10% level. (d) The result is significant at a 5% level but not at a 1% level.
