5. Mary bought a pack of candy. The manufacturer claims that 30% of the candies
manufactured are red. In her pack, 14 of the 60 candies are red. She ran a
simulation of 300 samples, assuming the manufacturer is incorrect. The results are
shown below.
Frequency

Based on the simulation, determine the middle 95% of plausible values that the
proportion of red candies in the pack is within.
Based on the simulation, is it unusual that Mary's pack had 14 red candies out of
a total of 60? Explain.
