What would happen (other things being equal) to a confidence interval if you calculated a 99% confidence interval rather than a 95% confidence interval? Question 11 options: It will not change. It will be wider. It will be narrower.
What would happen (other things being equal) to a confidence interval if you calculated a 99% confidence interval rather than a 95% confidence interval?
As the level of confidence increases, The interval becomes wider.

Which one is the right one? Keeping all the other things the same, if there is an increase in the sample size the confidence interval would become O No change Wider 0 Change from a 99% to a 95% level of confidence Narrower
when a 99% confidence interval is calculated instead of a 95% confidence interval with n being the same, the margin of error will be larger, smaller, the same, or cannot tell because it depends on other information as well?
QUESTION 3 All things being equal, which is correct? As the confidence level increases, the margin of error gets larger. As the sample size increases, the confidence interval gets wider. As the standard deviation increases, the margin of error gets smaller. As the sample mean increases, the margin of error gets larger. Which of the following is correct? As the sample size increases, the confidence level decreases. As the confidence level increases, the width of the confidence interval decreases. As...
QUESTION 1 Suppose we have a sample size of 100 and calculate a confidence interval. What will happen to that interval if we then get a sample size of 200 (all else equal). It will become narrower It will become wider. It will remain the same, because the mean is not changing It will get closer to 1.96. QUESTION 1 Suppose we have a sample size of 100 and calculate a confidence interval. What will happen to that interval if...
Suppose you construct a 96% confidence interval for a population mean from a normal distribution with known . Scenario 1: If you increase the size of the sample while keeping the same 95% level of confidence, how would your confidence interval be affected? Circle answer. a. would be wider b. would be narrower c. there would be no change d. no way to know without additional information Scenario 2: If you increase the level of confidence from 96% to 99%...
11. [6 points] Using a sample of 100 children, a 95% confidence interval for the proportion of children under the age of 18 who had asthma was constructed to be (0.085,6.23) a) Which of the following would produce a confidence interval which is narrower than the constructed 95% confidence interval? Sample 150 children rather than 100, (Maintain the confidence level at 95%) Sample only 80 children rather than 100, (Maintain the confidence level at 95%) . (b) Which of the...
Which must be true about a 95% confidence interval based on a given sample? I. The interval is wider than a 99% confidence interval would be. II. The interval contains 95% of the population. III. The interval is narrower than a 90% confidence interval would be.
Question 14 (1 point) Suppose you compute a 95% confidence interval. What will happen to the confidence interval if you increase the confidence level to 99%? O A) Confidence interval will decrease if the confidence level becomes wider OB) Confidence interval will become wider if the confidence level is increased O C) Confidence interval will increase if the confidence level becomes wider OD) Confidence interval will become narrower if the confidence level is increased Previous Page Next Page Page 10...
3. Other things being equal, what will happen to bond prices if riskiness of bond relative to other assets decreases? (Analyze the bond market using the graph below by shifting the demand or supply or both.) Price Bond quantity
Each of the following is a confidence interval for u = true average (i.e., population mean) resonance frequency (Hz) for all tennis rackets of a certain type: (117.6, 118.4) (117.4, 118.6) (a) What is the value of the sample mean resonance frequency? Hz (b) Both intervals were calculated from the same sample data. The confidence level for one of these intervals is 90% and for the other is 99%. Which of the intervals has the 90% confidence level, and why?...
