You are preparing to conduct a research study for a shopping mall owner. Research that you have reviewed indicates that people shop more during rain than during other types of weather. One of the research sources you are using is a histogram, from a credible source, that shows the mean rain in the same geographical area in which the mall is located has increased over the last five years.
· What is the probability that the mean rain in the area will be higher this year than in the previous five years?
· How will you briefly describe the research to the mall owner?
