When Brett Kavanaugh was nominated to be a Supreme Court justice, a survey of 1029 Americans showed that 51.1% of themdisapproved of Kavanaugh. A newspaper published an article with this headline: "Majority of Americans Disapprove of Kavanaugh." Use a0.10 significance level to test the claim made in that headline. Use the P-value method. Use the normal distribution as an approximation tothe binomial distribution.Let p denote the population proportion of all Americans who disapproved of Kavanaugh.

A Pew Research Center poll asked 1102 teenagers (12- to 17-year-olds) in the United States if they have a cell phone. Of the respondents, 71% said yes. Identify the population, the sample, and the sample statistic. Is the sampling distribution normally distributed? What is the mean and standard deviation of the sampling distribution? Find the cutoff for the highest 0.15% of sample proportions. Find the cutoffs for the middle 95% of sample proportions.

A leading magazine (like Barron's) reported at one time that the average number of weeks an individual is unemployed is 35.2 weeks. Assume that for the population of all unemployed individuals the population mean length of unemployment is 35.2 weeks and that the population standard deviation is 5.6 weeks. Suppose you would like to select a random sample of 29 unemployed individuals for a follow-up study. Find the probability that a single randomly selected value is between 33.1 and 33.8.

A television show conducted an experiment to study what happens when buttered toast is dropped on the floor. When 54 buttered slices of toast were dropped, 31 of them landed with the buttered side up and 23 landed with the buttered side down. Use a 0.05 significance level to test the claim that toast will land with the buttered side down 50% of the time. Use the P-value method. Use the normal distribution as an approximation to the binomial distribution. After that, supposing the intent of the experiment was to assess the claim that toast will land with the buttered side down more than 50% of the time, write a conclusion that addresses the intent of the experiment. ..... Let p denote the population proportion of all buttered toast that will land with the buttered side down when dropped. Identify the null and alternative hypotheses to test the claim that buttered toast will land with the buttered side down 50% of the time. Ho: p H1: P (Type integers or decimals. Do not round.)
