Rewrote the variables, trying to restore sanity.The confidence interval for Friday was just made up, so it disagreed with the given data.Now we pick population means and ranges for Monday and Friday, then generate data from those, and finally calculate the sample statistics. Fortunately, around 50% of the time the confidence intervals overlap.Still need to write advice, and proofread the question text.
