When Brett Kavanaugh was nominated to be a Supreme Court justice, a survey of 1043 Americans showed that 50.6% of them disapproved of Kavanaugh. A newspaper published an article with this headline: "Majority of Americans Disapprove of Kavanaugh." Use a 0.01 significance level to test the claim made in that headline. Use the P-value method. Use the normal distribution as an approximation to the binomial distribution. Let p denote the population proportion of all Americans who disapproved of Kavanaugh. Identify the null and alternative hypotheses. Ho: P H₁: p (Type integers or decimals. Do not round.) Identify the test statistic. z= (Round to two decimal places as needed.) Identify the P-value. P-value= (Round to three decimal places as needed.) State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. the null hypothesis. There sufficient evidence to the claim that a majority of Americans disapproved of Kavanaugh.

A binomial experiment is given. Decide whether you can use the normal distribution to approximate the binomial distribution. If you can, find the mean and standard deviation. If you cannot, explain why. A survey found that 83% of parents of teenagers have taken their teenager's cell phone or Internet privileges away as a punishment. You randomly select 17 parents of teenagers and ask them whether they have taken their teenager's cell phone or Internet privileges away as a punishment. Select the correct answer below and, if necessary, fill in the answer boxes to complete your choice. A. Yes, the mean is and the standard deviation is (Round to two decimal places as needed.) B. No, because np < 5. C. No, because nq < 5.

Consider a binomial distribution. About 61% of all Salinas residents own a smart phone. Find the mean number of residents  own a smart phone when selecting a sample of n = 53 residents.

A television show conducted an experiment to study what happens when buttered toast is dropped on the floor. When 43 buttered slices of toast were dropped, 23 of them landed with the buttered side up and 20 landed with the buttered side down. Use a 0.10 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 0.5 0.5 (Type integers or decimals. Do not round.)…

Last​ year, a person wrote 118 checks. Let the random variable x represent the number of checks he wrote in one​ day, and assume that it has a Poisson distribution. What is the mean number of checks written per​ day? What is the standard​ deviation? What is the​ variance?

A large car dealership claims that 47% of its customers are looking to buy a sport utility vehicle (SUV). A random sample of 61 customers is surveyed. What is the probability that less than 40% of the sample are looking to buy an SUV? Your answer should be from the cumulative normal distribution table.

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. P(33.1 < X < 33.8) = 0.0475 29 is Find the probability that a sample of size n randomly selected with a mean between 33.1 and 33.8. Р(3.1 < М < 33.8) - Enter your answers as numbers accurate to 4 decimal places.

The starting salaries of financial accountants are positively skewed, with a mean of $52,000 and a standard deviation of $12,000. The starting salaries of cost accountants have a slightly skewed distribution, with a mean of $58,000 and a standard deviation of $14,000. A random sample of 40 financial accountants and a random sample of 50 cost accountants are selected. What is the probability that the starting salaries of the financial accountants will not exceed the starting salaries of A Round the final cost accountants? answer to four decimal places.
