B. True or false. Read and understand the questions. Wrtte TIf the statement is true otherwise write F if the statement is false. 1. The confidence interval is centered about the point estimate of the sample and indicates the probability that the sample statistic is located within. the interval. 2. The formula for determining the appropriate sample size to use for calculating the confidence interval for the population mean is simply a matter of solving for n in the formula for e. 3. A 100% confidence interval can be calculated for large samples such that the resulting interval is guaranteed to contain the population parameter.

Question
B. True or false. Read and understand the questions. Writte TIf the staterment is true otherwise write F if the statement is false. 1. The confidence interval is centered about the point estimate of the sample and indicates the probability that the sample statistic is located within. the interval. 2. The formula for determining the appropriate sample size to use for calculating the confidence interval for the population mean is simply a matter of solving for n in the formula for e. 3. A 100% confidence interval can be calculated for large samples such that the-resulting interval is guaranteed to contain the population parameter. 4. To find the proper value in the Z tables for a two-sided confidence interval, remember each tail is alpha/2. 5. As the value of alpha increases, the width of the confidence interval decreases. 6. As the sample size increases, the width of the confidence interval increases. 7. "Alpha" is the designation for the proportion of values outside the confidence interval so that (1-alpha) indicates the confidence interval. 8. The further the confidence interval differs from the sample mean (point estimate), the less confident you can be that the population mean falls within that interval of values. 9. All confidence intervals are two-sided, with alpha/2 associated with each tail of the distribution. One-sided confidence intervals do not exist. 10. If a particular characteristic (X) of items in a sample meet a certain criferia, then the proportion of these items in the sample is represented as p = X/n.
