(--) ? Not secure ! Done 14 2018 Step 1: (1423) A National Football League kicker has made 80% of his field goal attempts in the past. This season he attempts 20 field goals. The attempts differ widely in distance, angle, wind, and so on. Is it reasonable to expect that a binomial distribution will at least approximately describe the number of successful field goals? Explain your answer. The number of successes doesn't have a binomial distribution. The attempts differ widely in distance, angle, wind, and so on, thus the probability of a success is not the same for each attempt. The number of successes has a binomial distribution. The attempts are independent and the probability of a success is the same for each attempt. The number of successes doesn't have a binomial distribution. The attempts differ widely in distance, angle, wind, and so on, thus the attempts are not independent. O The number of successes doesn't have a binomial distribution. It has a normal distribution, because of the number of attempts. Step 2: A National Basketball Association player has made 80% of his free-throw attempts in the past. This season he takes 150 free throws. ketball free throws are always attempted from 15 feet away with no interference from other players Is it reasonable to expect that a binomial distribution will at least approximately describe the number of successful free-throws? Explain your The number of successes doesn't have a binomial distribution because the number of observations is not fixed. g: 7:04:00 Start: 4:53 PM Type here to searchExplanation / Answer
Step 1:
The number of successes has a binomial distribution. The attempts are independent and the probability of a success is the same for each attempt.
Step 2:
Here, the number of successes is more likely to be at least approximately binomial distributed. There is a fixed number of independent throws - 150 and it is reasonable to assume that all have approximately the same probability of success, 0.8.
