A box contains 6 red balls, 5 green balls, and 2 blue balls. You pull 2 balls from the box (one at a time) WITHOUT replacement. **LEAVE ALL ANSWERS AS FRACTIONS** Find the probability of the following: a.) P(Red on 1st ball AND Red on 2nd ball) =l | b.)P[Green on 1st ballAND Red on 2nd balll=| l c.) P(Blue on 'lst ball AND Green on 2nd ball] =l | d.) What is the probability of drawing 2 green balls in your 2 pulls?' | e.) What is the probability of selecting a red ball on your second pull, given a red ball was already selected on the first pull?' l f.) What is the probability of drawing one red ball and one green ball (in either order)?| l g.) What is the probability or selecting two balls of the same color? l | h.) What is the probability or selecting two balls of different colors? l | Below is data collected on how long Statistics students study per week and the percentage of students who pass the course for the given arrount of study time: Study Time in hours per week (:3): O 3 5 10 % of students who pass Statistics (y): 10 55 7O 95 a.) Would you say the data has a Positive correlation or Negative correlation? '3 Positive 0 Negative b.) Compute Ex, Zy, Z332, ny Ex = iv = 2x2 = m = c.) Find the slope and the yintercept of the best fit regression line. (rou nd to 2 decimal places on slope and y-int) y=mm+b y: X+ d.) Based on your answer from part c, what would you estimate the % completion rate is for students who study for 3.5 hours per week? Round to nearest %
