Question 16 Given the following data pairs (x,y), find the regression equation. (1, 1.24), (2, 5.23), (3, 7.24), (4, 7.60), (5, 9.97), (6, 14.31), (7, 13.99), (8, 14.88),(9, 18.04), (10, 20.70) O y = 0.49x O y= 1.98x + 0.436 O y = 0.490x - 0.053 O y = 2.04xQuestion 17 Alice is riding the train to her job in Paris, France. She accidentally purchased a ticket for zone 4, but she is traveling to zone 5. She has decided to risk it and stay on the train until zone 5 with the incorre ticket. If the transit authorities check tickets on the train, she will have to pay a fine. Alice estimates that there is a 5% percent chance that the transit authorities will check tickets. The fine for having the wrong ticket is 300 euros. The ticket she purchased cost her 5 euros. Find the total expected cost of Alice's train ride. 19.5 305. 300 O 20Question 18 In a drawer, there are 4 white socks, 3 blue socks, and 5 grey socks. Two socks are picked randomly one after the other. What is the possibility that both the socks are of the same color?
