The popular candy Skittles comes in five colors. According to the Skittles website, the five colors are evenly distributed in the population of Skittle candies, so each color makes up 20% of the population. Suppose we purchase a large bag of Skittles. Assume that this size bag always has 100 candies. In this particular bag 30 are green. 30 out of 100 is 30%. Is this a surprising result? Choose an option, and explain.
a. Yes, this is surprising. Random samples with this much error are unusual.
b. Yes, this is surprising. We expect to see that 20% of candies are green.
c. No, this is not surprising. This is about one and a half standard errors above 20%.
d. No, this is not surprising. We expect random samples to vary.

If p(x) is the total value of the production when there are x workers in a plant, then the average productivity of the workforce at the plant is a(x) = p(x) x . (a) find a'(x). a'(x) = xp'(x) − p(x) x a'(x) = xp'(x) − p(x) x2 a'(x) = p'(x) − p(x) x a'(x) = xp'(x) − p'(x) x2 a'(x) = p'(x) − xp(x) x2 why does the company want to hire more workers if a'(x) > 0? a'(x) > 0 ⇒ a(x) is ; that is, the average productivity as the size of the workforce increases. (b) if p'(x) is greater than the average productivity, which of the following must be true? p'(x) − xp(x) > 0 p'(x) − xp(x) < 0 xp'(x) − p'(x) > 0 xp'(x) − p(x) < 0 xp'(x) − p(x) > 0
