Annual high temperatures in a certain location have been tracked for a sample of 7 years. Let X represent the year and Y the high temperature (in C ). X y 5 23.45 6 26.02 7 26.79 8 31.06 9 30.53 10 33.8 11 34.07 Calculate the correlation coefficient. (Round to three decimal places. ) r = Let's test the significance of the correlation coefficient at a = 0.01 significance level. Ho: There is not a significant relationship between the year and high temperature, i.e., p = 0. Ha : There is a significant relationship between the year and high temperature, i.e., p * 0. a. Calculate the test statistic. Round to three decimal places. b. Calculate the p-value. Round to four decimal places. p-value = c. Make a decision
