11.8 The following table lists results from an experiment designed to test the ability of dogs to use their extraordinary sense of smell to detect malaria in samples of children's socks (based on datapresented at an annual meeting of the American Society of Tropical Medicine, by principal investigator Steve Lindsay). The accompanying information shows the hypotheses and TI-83/84 Pluscalculator results for the experiment. Assume that the hypothesis test requirements are all satisfied.

Find the Type II error given that the null hypothesis, H0, is: there are no more than 15% of structures in the county were built without permits.And, the alternative hypothesis, Ha, is: a building inspector claims that more than 15% of structures in the county were built without permits. Select the correct answer below: The building inspector concludes that more than 15% of the structures in the county were built without permits when, in fact, no more than 15% of the structures were built without permits. The building inspector concludes that more than 15% of the structures in the county were built without permits when, in fact, more than 15% of the structures were built without permits.

12) The personnel director for a small firm thinks that employees may be more likely to use sick days on Monday and Friday resulting in three-day weeks. a) What is the appropriate null and alternate hypothesis to determine if sick day absences depend on day of the week? b) The personnel director obtains sick day data for the past year and summarizes the number of absences by day of the week in the table below. Use JMP software to test the hypothesis of part a) c) Using alpha = 0.05, draw a conclusion for the hypothesis test and state the conclusion in the context of the problem.

A manufacturer of hand-held calculators receives large shipments of printed circuits from a supplier. It is too costly and time-consuming to inspect all incoming circuits, so when each shipment arrives, a sample is selected for inspection. Information from the sample is then used to test H0: p = 0.01 versus Ha: p > 0.01, where p is the actual proportion of defective circuits in the shipment. If the null hypothesis is not rejected, the shipment is accepted, and the circuits are used in the production of calculators. If the null hypothesis is rejected, the entire shipment is returned to the supplier because of inferior quality. (A shipment is defined to be of inferior quality if it contains more than 1% defective circuits.) In this context, define Type I and Type II errors. (Select all that apply.) a. A Type I error is obtaining convincing evidence that more than 1% of a shipment is defective when in fact (at most) 1% of the shipment is defective. b. A Type I error is not…
The following are the hypotheses for a test of the claim that college graduation statue and cola preference are independent. H0: College graduation status and cola preference are independent. H1: College graduation status and cola preference are dependent. If the test statistic is χ2=0.579 and the critical value is χ2=5.991, what is your conclusion about the null hypothesis and about the claim? A. Fail to reject the null hypothesis. There is sufficient evidence to warrant rejection of the claim that college graduation status and cola preference are independent. B. Reject the null hypothesis. There is not sufficient evidence to warrant rejection of the claim that college graduation status and cola preference are independent. C. Fail to reject the null hypothesis. There is not sufficient evidence to warrant rejection of the claim that college graduation status and cola preference are independent. D. Reject the null hypothesis. There is sufficient…

1. An original claim is made that more than 50% of American consumers are not comfortable with the use of drone delivery for merchandise. Hypothesis testing results in Failure to Reject the Null hypothesis. Using Figure 8- 5 on page 366 of the text, clearly state the final conclusion reached from this hypothesis test.
If a researcher decides to reject the null hypothesis using an alpha level of α = 0.05 at the conclusion of a hypothesis test, then they would include the statement of "p < 0.05" when writing their research report.
