Consider the following simple random sample of 6 paired values (x,y):

x 3 13 21 24 1 12

y 9 29 43 47 3 26

With a 1% significance level, we wish to test the claim that there is a linear correlation between the variables x and y. Write the claim and the opposite of the claim in symbolic forms. (Use rho for the population linear correlation coefficient and whichever symbols you need of "<", ">", "=", "not =").

Claim:_______________

Its opposite:_______________

State the null and alternative hypotheses for testing such a claim. (Use rho for the population linear correlation coefficient and whichever symbols you need of "<", ">", "=", "not =").
