It is possible all of these intervals are in- correct. For example, if v = 100 then ev- ery interval is incorrect. But what is the maximum number of these intervals tha can be correct? What values of v wil give this maximum number of correct in- tervals? (Hint: The answer is not any of the four confidence intervals.)

Recall that a confidence interval is too small if che number being estimated is larger than every number in the confidence interval. Similarly, a confidence interval is too large if the number peing estimated is smaller than every number in the confidence interval. Each of four researchers selects a random sam- ple from the same population. Each researcher calculates a confidence interval for the median of the population. The intervals are below. [14, 31], [20, 29], [10, 23], and [25, 35]. (a) Nature announces, “Two of the intervals are correct and two are too large." Given this information, what is the narrowest in- terval that is known to contain the median? (Hint: The answer is not any of the four confidence intervals.) (b) Nature announces, “Two of the intervals are correct, one interval is too small and one interval is too large." Given this infor- mation, what is the narrowest interval that is known to contain the median? (Hint: The answer is not any of the four confi- dence intervals.)
