An Olympic archer misses the bull's eye 14% of the time. Assume each shot is independent of the others. If she shoots 7 arrows, what is the probability of each of the results described in parts a through f below? c) Her first miss comes on the second or third arrow The probability is 0.2239 (Round to four decimal places as needed.) d) She misses the bull's-eye exactly 3 times. The probability is 0.0525. (Round to four decimal places as...
Ch6 Q7 An Olympic archer misses the bull's-eye 11% of the time. Assume each shot is independent of the others. If she shoots 9 arrows, what is the probability of each of the results described in parts a through f below? a) Her first miss comes on the third arrow. The probability is __________________ (Round to four decimal places as needed.) b) She misses the bull's-eye at least once. The probability is __________________ (Round to four decimal places...
An Olympic archer is able to hit the bull's-eye 84% of the time. Assume each shot is independent of the others. She shoots 6 arrows. a) How many bull's-eyes do you expect her to get? b) What is the standard deviation? c) If she keeps shooting arrows until she hits the bull's-eye, how long do you expect it will take?
An Olympic archer is able to hit the bull's-eye 89% of the time. Assume each shot is independent of the others. She shoots 8 arrows. a) How many bull's-eyes do you expect her to get? b) What is the standard deviation? c) If she keeps shooting arrows until she hits the bull's-eye, how long do you expect it will take?
An archer is able to hit the bull's-eye 58% of the time. If she shoots 8 arrows, what is the probability that she gets exactly 4 bull's- eyes? Assume each shot is independent of the others. 0.2465 0.1131 0.1433 0.00352
An archer is able to hit the bull's-eye 32% of the time. If she shoots 9 arrows, what is the probability that she does not get exactly 4 bull's-eyes? Assume each shot is independent of the others. Express your answer as a percentage rounded to the nearest hundredth.
an archer is able to hit the bulls-eye 50% of the time. if she shoots 8 arrows, what is the probability that she gets exactly 4 bulls-eyes? Assume each shot is independent of the others.
An Olympic archer can hit the bullseye 89% of the time. Assuming each shot is independent, a) find the probability the first bullseye is on her third shot. b) find the probability she has to shot at least 3 times prior to the first bullseye. c) compute E(X), V(X), and ?.
A) The distribution of exam scores for Statistics is normally distributed with a mean of 78 and a standard deviation of 5.2. What is the z-score for a raw score of 85? Round to the nearest hundredth. B) An Olympic archer is able to hit the bull’s eye 80% of the time. Assume each shot is independent of the others. She will shoot 6 arrows. Let X denote the number of bull’s eyes she makes. Find the standard deviation of...
9. Assume that a procedure yields a binomial distribution with a trial repeated n times. Use (1 point) the binomial probability formula to find the probability of x successes given the probability p of success on a single trial. Round to three decimal places. n=64, x=3, p=0.04 O 0.091 O 0.139 O 0.221 O 0.375 6. Find the indicated probability. (1 point) An archer is able to hit the bull's-eye 53% of the time. If the archer shoots 10 arrows,...
