16. A 95% confidence interval for the proportion of Americans under the age of thirty who skip break- fast is found to be (0.2025, 0.2795). For each choice below, answer True or False: a. T or F There is a 95% probability that the true proportion of Americans under the age of thirty who skip breakfast is between 20.25% and 27.95%. F If this study were to be repeated many times with samples of the same size, then 95% of the time the true proportion will be between 0.2025 and 0.2795, on average. b. T or e. T or F If we were to construct one hundred confidence intervals, then 95% of them would contain the true proportion of Americans under the age of thirty who skip break- fast, five percent would not.

Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.
