Based on a random sample of 120 rhesus monkeys, a 95% confidence interval for the proportion of rhesus monkeys that live in a captive breeding facility and were assigned to research studies is (0.67, 0.83). Which of the following is true?
A. If we used a different confidence level, the point estimate would remain in the center of the confidence interval.
B. A larger sample size would yield a wider confidence interval.
C. The margin of error for the confidence interval is 0.16.
D. 95 of the sampled monkeys were assigned to research studies.

At a confidence level of 95% a confidence interval for a population proportion is determined to be 0.65 to 0.75. If the sample size had been larger and the estimate of the population proportion the same, this 95% confidence interval estimate as compared to the first interval estimate would be Group of answer choices narrower. the same. wider.

A 95% confidence interval for a population proportion was constructed using a sample proportion from a random sample. Which of the following statements are correct? Select all that apply If we were to use a 90% confidence level, the confidence interval from the same data would produce an interval wider than the 95% confidence interval. There is a 95% chance that the 95% confidence interval actually contains the population proportion. We don't...

Based on a random sample of one-bedroom apartments in Boston, the 95% confidence interval for the average monthly rent of all one-bedroom apartments in Boston is ($1700, $2000). (a) Give the margin-of-error in the study. (b) Is it possible that the average monthly rent of all one-bedroom apartments in Boston is $1600? (c) If there were more apartments in the sample, would the 95% confidence interval be longer, shorter or remain the same? (d) If the number of apartments in...

A simple random sample of 120 vet clinics in Adelaide reveals that the vast majority of them only treat small pets (dogs, cats, rabbits, etc) and no large animals (cows, horses, etc). Of the 120 clinics sampled, 88 responded that they do not treat large animals at their clinics. If a 95% confidence interval were calculated instead of a 90% confidence interval for p, what would happen to the width of the confidence interval? Select one: a. It would be...
