(a) Look at 50 vehicles in a parking lot near you. Count the number that are SUVs (state your definition of SUV). Use any sampling method you like (e.g., the first 50 you see). (b) Construct a 95 percent confidence interval for the true population proportion of SUVs. (c) What sample size would be needed to ensure an error of ± 0.025 with 98 percent confidence? (d) Would the proportion be the same if this experiment were repeated in a university parking lot?
