Composite SAT scores and composite ACT scores are thought to be correlated for students coming into their first year of college. Given the dataset below, calculate the Pearson's correlation coefficient for the dataset below and interpret what that means. ACT SAT 35 881 18 997 17 980 12 917 31 963 23 887 26 964 1 862 14 844 107911) The correlation is -0.395 . There is a moderate positive linear association between ACT and SAT .
2) The correlation is 0.395 . There is a perfect positive linear association between ACT and SAT .
3) The correlation is -0.395 . There is a moderate negative linear association between ACT and SAT .
4) The correlation is 0.395 . There is a moderate positive linear association between ACT and SAT .
5) The correlation is 0.395 . There is a moderate negative linear association between ACT and SAT .

For problems 7–10, state a reasonable domain for the problem statement, find the inverse functionf –1(x), and identify the independent and dependent quantities of the inverse. gary is jogging. the total distance he has traveled, in miles, can be estimated using the functionf(x) = 9x, where x is his jogging time in hours. camryn sells computers. she earns commission for her computer sales plus a fixed wage for each day she works. her daily earnings, in dollars, can be estimated using the functionf(x) = 0.15x + 50, where x represents her computer sales in dollars. the distance a motorboat travels, in meters, can be estimated using the equation f(x) = 1.9x2, wherexisthetimeinseconds,for0≤x≤10. a rock band is selling tickets to a concert at a theater. the band earns money for each ticket sold, but has to pay some of the earnings to the theater. the total money earned by the band can be estimated using the function f(x) = 7.5x – 300, where x is the number of tickets sold.
