Lois is studying a possible relationship between the market price of gold and industrial diamonds. She determined that in her study, x would be the market price of one ounce of gold and y would be the market price of industrial diamonds (price per carat). A random sample of six end-of -day closing prices on the New York Stock Exchange gave a sample correlation of r = 0.70. Assume that x and y are normally distributed and test the claim that there exists a positive correlation between the market price of gold and industrial diamonds. Use a 5% level of significance. Explain your answer.
