What will happen to the length of a confidence interval if the sample proportion is increased?
| a | unable to tell |
| b | increase the length |
| c | decrease the length |
| d | stay the same |
Homework Answers
We will be unable to tell the effect of increase in sample proportion in the length of confidence interval as the standard error depends on ?p(1-p) where p is the sample proportion.
Thus,(a) unable to tell is the correct option.

For confidence interval computations, if the sample size is increased, we expect the margin of error to: a. Increase b. Decrease c. stay the same The company you work for produces automotive parts for GM. A certain machine that makes a cutout in a piece of steel averages a cut size of 203.2085 mm with a standard deviation of 0.2083 mm. A random sample of 66 is taken from the population. What is the distribution of the sample mean? Approximately...

Suppose you compute a 97% confidence interval. What will happen to the confidence interval if you decrease the confidence level to 96%? The confidence interval will widen. The confidence interval will narrow. The width of the confidence interval will stay the same.
What will happen to the width of a confidence interval if there is an increase in the: confidence level, sample size, and standard deviation?
Answer and explain. If all other quantities remain the same, what will happen to the width of a confidence interval if there is an increase in the:confidence level;sample size; andstandard deviation

A newspaper conducts a poll to determine the proportion of voters who favor passage of a new handgun safety law. From the poll results, a 95% confidence interval estimate of the proportion is found: (0.514, 0.574). What proportion of those polled favored the safety law? (think point estimate) Answer: What was the margin of error for their results? Answer What was the margin of error for their results? Answer: If the confidence level was raised to 98%, but the sample...

when the level of confidence and sample proportion remain the same, a confidence interval for a population proportion based on a sample of n=200 will be narrower than a confidence interval based in a sample of n=100. True or False

If you are constructing a confidence interval for a population mean, for the same confidence level, the width of the confidence interval will __________ as the sample size increases. Decrease Increase Stay the same Depends on the sample size

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.
