Part A:
Given that 18% of the population is left handed, in a sample of 6 customers, we expect to see 0.18 x 6 = 1.08 lefties.
Part B:
Given that the proportion of lefties is 18% or 0.18 and the proportion of non-lefties is 100 - 18 = 82% or 0.82.
Since the sample size is 6, the sample standard deviation is given by:
