(Round your numerical values to five decimal places.) (b) Compute the coefficient of determination. (Round your answer to four decimal places.) Explain its meaning. (Give your answer as a percent. Round your answer to two decimal places.) The value of the coefficient of determination tells us that % of the variability in -?- | has been explained by the least squares line. (c) Compute the correlation coefficient between the price and the number of pages. (Round your answer to four decimal places.) Test to see if x and y are related using the t-test. Use a = 0.10. State the null and alternative hypotheses. (Enter != for # as needed.) Ho H 2
