The table shows the number of wins of two high school softball teams over the past ten years. which statement best compares the interquartile range (iqr) of the two sets of data?
a) eastfield's data shows less variability, since eastfield's iqr is 2.625 times greater than westfield's iqr.
b) westfield's data shows less variability, since westfield's iqr is 2.625 times greater than eastfield's iqr.
c) eastfield's data shows greater variability, since eastfield's iqr is 4.25 times greater than westfield's iqr.
d) westfield's data shows greater variability, since westfield's iqr is 4.25 times greater than eastfield's iqr.

Arandom sample of n = 25 observations is taken from a n(µ, σ ) population. a 95% confidence interval for µ was calculated to be (42.16, 57.84). the researcher feels that this interval is too wide. you want to reduce the interval to a width at most 12 units. a) for a confidence level of 95%, calculate the smallest sample size needed. b) for a sample size fixed at n = 25, calculate the largest confidence level 100(1 − α)% needed.
