Question 58

Multiple Choice

Golf course designer Roberto Langabeer is evaluating two sites,Palmetto Dunes and Ocean Greens,for his next golf course. He wants to prove that Palmetto Dunes residents (population 1) play golf more often than Ocean Greens residents (population 2) . Roberto commissions a market survey to test this hypothesis.The market researcher used a random sample of individuals from each suburb,and reported the following: Golf course designer Roberto Langabeer is evaluating two sites,Palmetto Dunes and Ocean Greens,for his next golf course.
