Flag question: Question 24 Compared with a 95% confidence interval, a 99% confidence interval would result in which of the following? Group of answer choices A.a wider range of values in the confidence interval B.the same range of values in the confidence interval C.a smaller range of values in the confidence interval D.a range that cannot be determined in the confidence interval
Explain which would result in a wider large-sample confidence interval for p: a 90% confidence level or a 95% confidence level? (Hint: Consider the confidence interval formula.) a. For any given sample, the 90% confidence interval is wider than the 95% confidence interval because the z critical value for a 90% confidence interval is smaller than the z critical value for a 95% confidence interval. b. For any given sample, the 90% confidence interval is wider than the 95% confidence interval because the z critical value for a 90% confidence interval is larger than the z critical value for a 95% confidence interval. c. For any given sample, the 95% confidence interval is wider than the 90% confidence interval because the z critical value for a 95% confidence interval is smaller than the z critical value for a 90% confidence interval. d. For any given sample, the 95% confidence interval is wider than the 90% confidence interval because the z critical value for a 95% confidence interval…

You wind up taking a sample of 49 random observations while your friend's sample Is made up of 36 random observations. Which of the following is true? a. The total width of your confidence interval estimate is wider b. Your friend's interval has a greater degree of confidence C. The total width of your confidence interval estimate is narrower d. Your interval has a greater degree of confidence Calculations: 2.11 The width of a confidence Interval for a proportion will be: a. wider for a sample of size 100 than for a sample of size 50 b. wider for 90% confidence than for 95% confidence C. narrower for 99% confidence than for 95% confidence d. wider when the sample proportion is 0.50 than when the sample proportion is 0.20 Calculations 2.12 A sample of 50 students was taken from the local university.

A student calculates a 90% confidence interval estimate of p. Which of these options best describes the meaning of the 90% confidence level? A. There is a 0.10 probability that p is in the interval. B. If we collected many different samples and calculated a confidence interval estimate of p for each, then about 90% would contain the actual value of p. C. There is a 0.90 probability that the estimate is reasonable. D. There is a 0.90 probability that p is in the interval.

Suppose you calculate a 95% and 90% confidence interval for the true proportion of college students with student loan using the same data set. Which of the following must be true? a) The 95% confidence interval is wider than the 90% confidence interval. b) The 95% confidence interval is the same length as the 90% confidence interval. c) The 95% confidence interval is narrower than the 90% confidence interval. d) There is no way to tell from the given information.
In a survey of 2939 US Adults, 2439 say they hve contributed to a charity in the past 12 months. Construct the 95% confidence interval for the population proportion p in this sample.
The full question for part B is written down below. (b) The 90% confidence interval is (__,__). It does/does not seem likely that the population mean could be within 8% of the sample mean because 8% off from the sample mean would fall outside/inside the confidence interval. It does not/does seem likely that the population mean could be within 9% of the sample mean because 9% off from the sample mean would fall outside/inside the confidence interval.
1. What conclusions can you draw about the proportions of Satisfaction with Quality of Care from Nurses and Satisfaction with Quality of Care from Specialists from the chart? A. The confidence intervals overlap, so we can conclude that the proportions are significantly different. B. The confidence intervals do not overlap, so we can conclude that the proportions are significantly different. C. The confidence intervals do not overlap, so we cannot conclude that the proportions are significantly different. D. The confidence intervals overlap, so we cannot conclude that the proportions are significantly different. 2.
