D5: What happens to the width of your confidence interval as you increase your sample size?...
What happens to the width of a confidence interval if the sample size increases, but all other quantities involved (e.g., the coverage probability and population variance) remain fixed? Please provide both an intuitive and mathematical explanation of your answer
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
Increasing the confidence level of your confidence interval will have what effect on the width of the interval? It is impossible to tell. The width will decrease. The width will remain the same. The width will increase.
Which of the following does NOT correctly describe how the width of a confidence interval for a population mean changes when the population standard deviation is known? The interval changes if the sample size decreases. The interval changes if the sample size increases. The interval narrows if the sample size increases and confidence level stays the same. The interval widens if the sample size decreases and the confidence level stays the same. The interval widens if the sample size stays...
Increasing the confidence level causes the width of the confidence interval to increase, decrease, stay the same? [Negative marking will be applied for incorrect answers.]
Which of the following correctly describes how the width of a confidence interval for a population mean changes when the population standard deviation is known? There is no change if just the sample size increases. The interval widens if the sample size stays the same and confidence level decreases. The interval narrows if the sample size increases and confidence level stays the same. The interval narrows if the sample size decreases and confidence level stays the same. The interval widens...
Suppose we have an existing confidence interval for a population mean. If we increase the sample size by a factor of 100, what happens to the width of the confidence interval? a) It remains the same. b) It decreases by a factor of 100. c) It increases by a factor of 10. d) It decreases by a factor of 10.
QUESTION 12 "If you wish to decrease the width of a confidence interval, you may do which one of the following: " Reduce sample size. Reduce the size of the population. Decrease the level of confidence. Both b and c
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
12. What is one way to increase the length of any confidence interval? (a) Increase the sample size (b) Use a smaller confidence level (c) Both (a) and (b) are correct (d) Neither (a) nor (b) are correct
