Consider these four data sets.

set a: {32, 12, 24, 46, 18, 22, 14}
set b: {4, 12, 11, 14, 11, 5, 12, 13, 18, 14}
set c: {5, 4, 9, 12, 14, 26, 22, 18}
set d: {1, 1, 1, 2, 2, 3, 3, 4, 5, 6}

the sets that show a positive skew are sets
the sets that show a negative skew are

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.
