The SAT and the ACT are the two major standardized tests thatcolleges use to evaluate candidates. Most students take just one ofthese tests. However, some students take both. The data data311.datgives the scores of 60 students who did this. How can we relate thetwo tests? (a) Plot the data with SAT on the x axis and ACT on they axis. Describe the overall pattern and any unusual observations.(b) Find the least-squares regression line and draw it on yourplot. Give the results of the significance test for the slope.(Round your regression slope and intercept to three decimal places,your test statistic to two decimal places, and your P-value to fourdecimal places.) ACT = + (SAT) t = P = (c) What is the correlationbetween the two tests? (Round your answer to three decimalplaces.)
