CorpPlus is a large corporation with many employees. You work for the human resources department of CorpPlus and want to estimate the population proportion of all employees who say the corporation is a great place to work. So, you will survey a random sample of 95 employees from CorpPlus and ask them whether they think the corporation is a great place to work. Follow the steps below to construct a 99% confidence interval for the population proportion of all employees who say the corporation is a great place to work. (If necessary, consult a list of formulas.) (a) Click on "Take Sample" to see the results from the random sample. Take Sample Sample size: 0 Point estimate: 0 Critical value: 0 Compute 0.000 Says the corporation is a great place to work Enter the values of the sample size, the point estimate of the population proportion, and the critical value you need for your 99% confidence interval. (Choose the correct critical value from the table of critical values provided.) When you…

A statistics instructor randomly selected four bagn of oranges, each bag labeled 10 pounds, and weighed the bags. They weighed 9.5, 9.7,9.5, and 9.5 pounds. O Assume that the distribution of weights is Normal. Find a 95% confidence interval for the mean weight of all bags of oranges. Use technology for your calculations Answer parts a and b below. a. Choose the correct interpretation of the confidence interval below and, if necessary, fil in the answer boxes to complete your choice. OA. We are 95% confident the population mean is betweenand OB. We are 95% confident that the sample mean is between and OC. There is a 95% chance that all ntervals will be between and OD. The requirements for constructing a confidence interval are not satisfied.

University personnel are concerned about the sleeping habits of students and the negative impact on academic performance. In a random sample of 377 U.S. college students, 209 students reported experiencing excessive daytime sleepiness (EDS). Is there sufficient evidence to conclude that more than half of U.S. college students experience EDS? Use a 5% level of significance STATE: What is a 90% confidence interval estimate for the proportion of all of U.S. college students who experience excessive daytime sleepiness? PLAN: State the name of the appropriate estimation procedure (e.g. one-sample t confidence interval for estimating the mean difference) Note: You have already described the parameter being estimated in Part A, so you don't have to repeat it here.

The International Air Transport Association surveys business travelers to develop quality ratings for transatlantic gateway airports. The maximum possible rating is 10. Suppose a simple random sample of 50 business travelers is selected and each traveler is asked to provide a rating for the Miami International Airport.

Pharmaceutical companies promote their prescription drugs using television advertising. In asurvey of 80 randomly sampled television viewers, 10 indicated that they asked their physicianabout using a prescription drug they saw advertised on TV. Develop a 95% confidence interval for the proportion of viewers who discussed a drug seen on TV with their physician. Is it reasonable to conclude that 25% of the viewers discuss an advertised drug with their physician?
A study has been conducted of the airspeed of various bird species. You would like to specify the difference in airspeed. The following information is obtained. 1. What multiplier should I use for 95% confidence interval? 2. Can you construct a confidence interval for the difference? 3. Does that interval support the hypothesis that there is a difference in the airspeed of these two species?
2. You are going to construct a 90% confidence interval for the proportion ofadults that have a post-secondary education. You want the margin of errorto be .03. Your initial guess is that 35% of the population has a postsecondary education. What should the sample size be to achieve thismargin of error?
Suppose Devonna owns a national chain of day care centers. She believes that 62% of her students have been to the beach in the last year. She samples 152 children who are enrolled in her 15 day care centers in the state of Florida and finds out that 48 have been to the beach in the last year. From this data, she calculates the z-statistic. Next, she wants to calculate the z-confidence interval for the proportion. Indicate whether or not the requirements for the z-confidence interval for a proportion have been met, and select the reason or reasons why the requirements have or have not been met. The requirements have not have been met because the sample is not random. the sample is random. the setting is not binomial. there are not at least 10 successes and 10 failures. there are at least 10 successes and 10 failures. the setting is binomial.
In a study designed to determine whether there was a cluster of brain cancer cases at a Pratt & Whitney plant, record from 223,000 employees were studied and 723 employees with brain tumors were found. Treat those employees as a random sample and construct a 95% confidence interval estimate of the proportion of all adults who develop such tumors. write a brief statement interpreting that confidence interval.
An epidemiologist is worried about the prevalence of the flu in East Vancouver and the potential shortage of vaccines for the area. She will need to provide a recommendation for how to allocate the vaccines appropriately across the city. She takes a simple random sample of 330 people living in East Vancouver and finds that 30 have recently had the flu. For each of the following statements, specify whether the statement is a correct interpretation of the 95% confidence interval for the true proportion of East Vancouver residents who have recently had the flu. A. 9.09% (30/330) of East Vancouver residents have recently had the flu. B. There is a 95% probability that the true proportion of East Vancouver residents who have recently had the flu equals 30/330. C. If another random sample of 330 East Vancouver residents is drawn, there is a 95% probability that the sample proportion of East Vancouver residents who have recently had the flu equals 30/330. D. If many random samples of 330 East…
