An Olympic archer is able to hit a bulls-eye 86% of the time. Assume each shot is independent of the others. If she shoots 12 arrows, what is the probability that 18. She never misses?
19. She gets exactly 11 bulls-eyes?
20. She gets between 6 and 10 bulls-eyes?
21. She gets less than 8 bulls-eyes?
22. She gets at least 8 bulls-eyes?
23. She gets at most 9 bulls-eyes?
24. She gets between 9 and 12 bulls-eyes, inclusive?
25. What is the expected number of bulls-eyes for the 12 attempts?

Given are five observations for two variables, x and y. xi 1 2 3 4 5 yi 3 7 5 11 14 which of the following is a scatter diagrams accurately represents the data? what does the scatter diagram developed in part (a) indicate about the relationship between the two variables? try to approximate the relationship betwen x and y by drawing a straight line through the data. which of the following is a scatter diagrams accurately represents the data? develop the estimated regression equation by computing the values of b 0 and b 1 using equations (14.6) and (14.7) (to 1 decimal). = + x use the estimated regression equation to predict the value of y when x = 4 (to 1 decimal). =
