A cable company claims that 88% of its customers are fully satisfied with their service. A competitor,who believes the figure to be far lower conducts an independent survey of 350 of the company'scustomers and finds that 287 are fully satisfied. Using the competitor's survey data, a 95%confidence interval for the proportion of all of the company's customers that are fully satisfied wouldbeO (0.77, 0.87)O (0.78, 0.86)O (0.74.0.90)O (0.79, 0.85)

Given that Sample size n =350 Favorable cases x =287 Sample proportion p^=x/n =287/350 =0.82

In a survey of 40 students in an introductory statistics class, a professor asks how many states in the United States each student has visited. Using the data from the professor's sample, a 99% confidence interval for the average number of states all students at the professor's school have visited is found to be (6.78, 12.18). Determine whether each of the following statements is valid or invalid. You may assume that the sample is representative of all students at the professor's school. (a) We are 99% confident that the average number of states visited by the 40 students the professor surveyed is between 6.78 and 12.18. Valid Invalid (b) Based on the 99% confidence interval, there is evidence that the average number of states visited by all students at the professor's school is different from 16. Valid Invalid (c) We are 99% confident that the average number of states visited by all students at the professor's school is between 6.78 and 12.18. Valid Invalid (d)…
In September 2011, Gallup surveyed 1,004 American adults and asked them whether they blamed Barack Obama a great deal, a moderate amount, not much, or not at all for U.S. economic problems. The results showed that 53% of respondents blamed Barack Obama a great deal or a moderate amount. Calculate the 99% confidence interval for the proportion of all American adults who blame Barack Obama a great deal or a moderate amount for U.S. economic problems. O (0.504, 0.556) O (0.499, 0.561) O (0.489, 0.571) O The confidence interval cannot be determined from the information given.
A beverage company would like to determine if their drink is preferred to a rival company’s drink. They perform an experiment with 150 randomly selected individuals and have them taste test the two different drinks in a controlled environment so that each person's preference is independent of others. A 90% confidence interval for the proportion preferring their drink is (0.453, 0.587). Which of the following is the correct interpretation of this confidence interval? 90% of all consumers prefer this beverage company’s drink to their rival’s between 45.3% and 58.7% of the time. We’re 90% confident that between 45.3% and 58.7% of all consumers would prefer this beverage company’s drink to their rival’s drink. We’re 90% confident that there’s a 45.3% to 58.7% chance that a randomly selected person would prefer this beverage company’s drink to their rival’s drink. We’re 90% confident that the proportion of people in the sample who prefer this beverage company’s drink over their…

A survey collected data on attitudes toward the quality of customer service in retail stores. The survey found that 270 of the 750 American adults sampled felt that customer service is better today than it was two years ago. We wish to develop a 94% confidence interval for the proportion of American adults who feel customer service is better today than it was two years ago. What is the population? A) the 750 American adults sampled B) customer service representatives C) all American adults
