For a randomly selected policyholder, let X = the number of months between successive payments.In a comparative study of two new drugs, A and B, 350 patients were treated with drug A, and 225 patients were treated with drug B. (The two treatment groups were randomly and independently chosen.) It was found that 241 patients were cured using drug A and 157 patients were cured using drug B. Let p1 be the proportion of the population of all patients who are cured using drug A, and let p2 be the proportion of the population of all patients who are cured using drug B. Find a 90% confidence interval for −p1p2 . Then complete the table below. Carry your intermediate computations to at least three decimal places. Round your responses to at least three decimal places. (If necessary, consult a list of formulas.) What is the lower limit of the 90% confidence interval? What is the upper limit of the 90% confidence interval?The National Highway Association is studying the relationship between the number of bidders on a highway project and the winning (lowest) bid for the project.

Assuming we are trying to develop and sovle a waiting line system that can accomodate this increased leel of passenger traffic.In a public opinion survey, 60 out of a sample of 100 high-income voters and 40 out of a sample of 75 low-income voters supported a decrease in value-added tax, VAT. Conclude at the 5% level of significance that the population of voters favouring a VAT decrease differs between high- and low-income voters. (Where p1 is the proportion of all high-income voters who supported a decrease in VAT; p2 is the same for the low-income voters). The rejection region to test the above hypothesis at the 5% significance level (rounded off to two decimals) is: A. T < -1.96 B. T < -1.64 or Z > 1.64 C. Z < -1.96 or Z > 1.96 D. Z < -1.64 E.

This tendency may maximize the number of each parent’sgrandchildren (and thus help to ensure that its genetic code is preserved) since a healthy maleoffspring can win many mates, but a relatively unhealthy offspring has the best chance of mating ifit is female. In an experiment to examine this hypothesis, a group of 40 opossums were monitoredand 20 of them were given an enhanced diet. After a certain period of time, the opossums with theenhanced diet had raised 19 male offspring and 14 female offspring, and the opossums without theenhanced diet had raised 15 male offspring and 15 female offspring. Does this finding provideevidence in support of the Trivers-Willard hypothesis? (a) Describe the unknown parameters ?1 and ?2. Then state the null and…
