a)Median \(= 731, IQR = 870593 = 277\)
b)For the largest: number of visitors (940), there needs to be at least 7 staff members.
c)Because a box plot is appropriate display of this data.
If x is a binomial random variable, find the probabilities below by using the binomial probability table.
a) \(P(x < 11)\ for\ n = 15, p = 0.1\)
b) \(P(x \geq 11)\ for\ n = 25, p = 0.4\)
c) \(P(x = 2)\ for\ n = 20, p = 0.6\)
