Suppose you want to estimate the proportion of cars that are sport utility vehicles (SUVs) being driven in Kansas City, Missouri, at rush hour by standing on the corner of I-70 and I-470 and counting SUVs. You believe the figure is no higher than 0.40. If you want the error of the confidence interval to be no greater than .03, how many cars should you randomly sample? Use a 90% level of confidence.
We need at least 10 more requests to produce the answer.

Current Attempt in Progress Suppose you want to estimate the proportion of cars that are sport utility vehicles (SUVs) being driven in Kansas City, Missouri, at rush hour by standing on the corner of 1-70 and 1-470 and counting SUVs. You believe the figure is no higher than 0.40. If you want the error of the confidence interval to be no greater than 03, how many cars should you randomly sample? Use a 90% level of confidence.

NAIVIE. 1. A city currently does not have a National Football League team. 68.5% of all the city residents are in favor of attracting NFL team. a. A random sample 850 of the city residents is selected, and asked if they would want an NFL team. Describe the sampling distribution of p, the proportion of the residents who want NFL team. b. In the sample obtained in part a, what is the probability the proportion of residents who want NFL...
A highway safety institution conducts experiments in which cars are crashed into a fixed barrier at 40 mph. In the institute's 40-mph offset test, 40% of the total width of each vehicle strikes a barrier on the driver's side. The barrier's deformable face is made of aluminum honeycomb, which makes the forces in the test similar to those involved in a frontal offset crash between two vehicles of the same weight, each going just less than 40 mph. You are...
Consider a hypothetical experiment in which investigators randomly selected 58 men from the membership list of the Sacramento Valley Motorist Society and then randomly assigned each man either to a sports utility vehicle (each one the same model and year and with the same amount of cumulative miles) or to a sedan (each one also exactly like the other). The men, 29 in each group, were instructed to drive these cars 100 miles on Interstate 5 in California, ostensibly to...
The answer needs to be in a format that can be posted to a discussion board. I cant upload pictures of problems done out on paper Write a confidence interval problem using one of the options below. For whichever option you choose, gather the appropriate data and post your problem (without a solution) in the discussion topic. Allow time for your classmates to post their solutions, and then respond to your own post with the solution for others to check...

Question 21 3 pts Large Sample Proportion Problem. Surveys were conducted in multiple countries and respondents were asked if they felt political news was reported fairly. The data for the United States is that out of 1,000 sampled, 470 indicated yes, they felt political news was reported fairly. Suppose we want to construct a 99% confidence interval. What is the Bound of Error (BOE)? 0.0309 2.576 0.0407 0.4293 to 5107 Question 22 3 pts Large Sample Proportion Problem. Surveys were...
I dont know how to do the last part? could someone help me In a survey of 160 randomly sampled households, 72 report owning a dog. Find a 99% confidence interval for the proportion of all households that own a dog. Can you conclude with 99% confidence that the proportion of households that own a dog is greater than 40 percent? Justify your answer. How many households would have to be surveyed in order to estimate the actual proportion of...
