Confidence Interval question
True Or False.
Which of the following are true,which are false ?
A confidence interval estimate provides an idea of the likely size of the sampling error. |
A disadvantage of a point estimate (compared to interval estimates) is that increased precision achieved through an increased sample size is not reflected in such estimates. |
Given n and the population standard deviation, an increase in the confidence level for an interval estimate will make the interval narrower. |
To obtain a confidence interval estimate for the population mean when using the standard normal variable (Z) and knowing the population standard deviation, the sample size must be at least 30 or more. |
