A. Directions: Identify whether the given statement is True or False. Write Tif it is true; otherwise, write F _1. In estimating the population mean, it is better to have a larger confidence interval than a smaller interval. _2. The width of the confidence interval is the difference of the upper and lower limits. _3. The higher the level of confidence is used in the estimation process, the wider the length of the confidence interval is.

Question
A. Directions: Identify whether the given statement is True or False. Write T if it is true; otherwise, write F _1. In estimating the population mean, it is better to have a larger confidence interval than a smaller interval. _2. The width of the confidence interval is the difference of the upper and lower limits. _3. The higher the level of confidence is used in the estimation process, the wider the length of the confidence interval is. _4. The larger the variability of the population is, the wider the margin of error will be. _5. Point estimates are preferred than the interval estimate. _6. In the formula for the computation of the limits of the interval estimate, the lower limit corresponds to the value X + za· yn _7. When the margin of error is small, the confidence level is high. _8. The larger the sample size used in setting the interval estimate is, the narrower the resulting confidence interval will be. _9. A 90 % confidence level corresponds to a 10% margin of error. _10. The difference between the estimate and the parameter being estimated is called standard error.
