Assume we are given the following information for yields of corn (in bushels per acre): Median = 150 Lower quartile = 130 Upper quartile = 170 Lowest yield = 80 Highest yield = 250 Construct a box plot for these data. Based on this box plot, is the lowest yield of 80 bushels per acre a suspect or highly suspect outlier?

Suppose that 20% of the Labrador Retrievers in the U.S. have a particular genetic defect. We randomly select 7 Labs from the population consisting of all Labs in the U.S. What is the probability that at least 1 of the 7 dogs in this sample has the genetic defect?

The American Angus Association wants to determine the proportion of their members who breed their cows using artificial insemination (AI). They randomly sample 200 of their members and ask them whether or not they breed their cows using AI. 120 of the 200 members sampled said “yes”. The proportion of the 200 members who breed their cows using AI is an example of a ____________.
