... After computing a confidence interval, the user believes the results are meaningless because the width of the interval is too large. Which one of the following is the best recommendation? a. Increase the level of confidence for the interval. b. Discard the current data and try a different sample. c. ...

The Missing Link: Data Analysis with Missing Information
... improved by first stratifying the data into subgroups (by gender and age category, for example) and using the subgroup average. The primary drawback to this method is that non-response bias is ignored, and data are assumed to be MCAR, or MCAR within subgroups. Subjects who are too sick to attend an ...

Section 8.1 First Day Intro to CI and Confidence Levels
... Since our standard deviation is 4.5, 95% of all samples will produce an x-bar that is within 9 points of μ. Our x-bar was 461. We say that we are 95% confident that the true mean math SAT score for California high school seniors is between ...

There are some comments on simulation, and we mention transformations of random variables in the discrete case. The interested rea ...
