18.) 7.31 (you should be able to do this by hand)

19a.) 0 19b.) Yes – if any of the #’s deviate from the mean, the SD will be positive

20.) 76.81, 76, 71, 156.82, 12.52 (you can do this one on the calculator – square the SD to get the variance)

25a.) 25, 50 25b.) B 25c.) 40, 80

25d.) B’s is more symmetrical, A’s is skewed right. Their min ticket price is the same, but overall B’s has higher ticket prices. B’s also had a wider range of prices, so its SD would be greater.

26.) 20 is an outlier, since it is more than 1.5IQR (30) below Q1
