Out of the 430 respondents, 246 say they plan tovote for Ms. Peanut and the rest say they will not. Do we have enough evidence to say thatMs. Peanut has more than 50% of the population of Washington County planning to vote forher (at alpha=.05)?a) Set up the null and alternative (one-sided) hypothesis for a one-sample z-test for thisproblem.b) Use the formula below to calculate the z-statistic. Remember that p-hat is the proportionfrom your sample and po is your hypothesized proportion, .50 (or 50% as a percentage).Showyour work or describe the process for calculating the z-statistic.c) What is the one-tailed critical value for a one-sided z-test? (see table below). Comparethis value to the z-statistic from part b. Can we reject the null at alpha=.05? How do youknow?p - P.z =P(1 - P.)

Assume that adults were randomly selected for a poll. They were asked if they "favor or oppose using federal tax dollars to fund medical research using stem cells obtained from human embryos." Of those polled, 484 were in favor, 399 were opposed, and 121 were unsure. A politician claims that people don't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Exclude the 121 subjects who said that they were unsure, and use a 0.01 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.5. What does the result suggest about the politician's claim? Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho: p=0.5 H₁: p > 0.5 B. Ho: p=0.5 H₁: p<0.5 C. Ho: p0.5 H₁: p=0.5 D. Ho: p=0.5 H₁: p0.5

4. Suppose 1% of the people in California have a certain type of cancer. The state isconsidering testing everyone in the state for the cancer. A person with the cancerhas a 95% chance of testing positive. A person without the cancer has a 10%chance of testing positive. If a doctor observes a positive test, what is theprobability that a patient has the cancer??
A special-interest group has conducted a survey concerning a ban on hand guns. Note: A rifle is a gun, but it is not a hand gun. The survey yielded the following results for the 1000 households that responded. 275 own a hand gun.431 own a rifle.493 supported the ban on hand guns.140 own both a hand gun and a rifle.199 own a rifle but no hand gun and do not support the ban on hand guns.78 own a hand gun and support the ban on hand guns.51 own both a hand gun and a rifle and also support the ban on hand guns. Exercise (a) How many of the surveyed households only own a hand gun and do not support the ban on hand guns? Exercise (b) How many of the surveyed households do not own a gun and support the ban on hand guns? Exercise (c) How many of the surveyed households do not own a gun and do not support the ban on hand guns?
Two different blood pressure medicines are being compared to determine if the average reduction in blood pressure is the same for each medication. The goal of the study is to determine if the medications differ. Twenty men age 50-60 years old are selected for the study. Ten men are chosen at random to receive the first medication and the other 10 men receive the second medication. Each of the 20 men is monitored for one month to determine the change in blood pressure over that time. Minitab provides the 95% confidence interval for (mu1 - mu2) (2.63, 14.18) a. Interpret this 95% CI. b. What assumptions (be specific) are necessary to construct this CI?

A poll released this week found that in a random sample of registered voters, 60% indicated that they think a fenmale "will run" for the presidency, 30% said a female “will not run," and 10% had “no opinion." When asked their opinions on whether or not a female could be elected, 66% of those who said a female "will run" thought a female could be elected; 25% of those who thought a female "will not run" thought a female could be elected; whereas, 20% of those who had no opinion said 4. that a female could be elected. а. [2] What percentage of registered voters (in this sample) thought that a female could be elected? [2] Given that a person thought that a female could be elected, what is the probability that this person said a female "will not run" for the presidency? b. [3] Given that a person thought that a female could be elected, which is more likely: that this person said a female “will not run" for the presidency or that this person said a female “will run" for the presidency? C.

A social psychologist hypothesized that a white person is more likely to cooperate with another person than a black person in a task requiring cooperation (this would be considerate an alternative hypothesis). To test this idea he conducted an experiment in which white subjects either worked on a task with a white person or black person (both of these “others” were confederates of the experimenter). Thirty-one subjects were randomly assigned to the “white-other” treatment (say this is treatment 1) and 31 were randomly assigned to the “black-other” treatment (this is treatment 2). If the mean cooperation scores, on a scale from 0 to 20, were 14 for those subjects in the “white-other” treatment and 12 for those in the “black-other” treatment, run an appropriate test to test the social psychologist’s hypothesis. Let us further say that the variance for the cooperation measure for the “white-other” treatment was = 2.48 and the variance for the “black-other” treatment was = 2.52. Use =0.05…

Of those polled, 481 were in favor, 396 were opposed, and 117 were unsure. A politician claims that people don't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Exclude the 117 subjects who said that they were unsure, and use a 0.05 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.5. What does the result suggest about the politician's claim?
An insurance company is thinking about offering discounts on its life insurance policies to nonsmokers. As part of its analysis, the company randomly selects 200 men who are 60 years old and ask them if they smoke at least one pack of cigarettes per day and if they have ever suffered from heart disease. 10 out of the 38 smokers had suffered from some type of heart disease and 12 out of 150 nonsmokers had suffered from some type of heart disease. Can we conclude at the 5% level of significance that smokers have a higher incidence of heart disease than nonsmokers? (Don't hand writing solution)
