Let X be the number of scoring chances that result in goals for a football team during n scoringchances. During many games, the team scores on 20% of the chances.a) Explain why it might be reasonable (at least as an approximation) to assume that X isbinomially distributed in this situation. Do this by going through each of the points that mustbe met for us to use the binomial distribution, assess whether it is reasonable for them to bemet here and specify any additional assumptions we need to make.

Suppose a random variable x, defines that the number of scoring chances that result in goals for a…

Suppose we want to estimate p, the proportion of undergraduate students who cheat. One strategy to estimate p is to sample n undergraduate students and ask each one the following question directly: Have you ever cheated in answering one of your class requirements (quizzes, exams, assignments, projects, etc.? Let Y₁, Y₂,, Y, denote the "1/0" ("yes/no") responses. a. What is the distribution of Y₁, i=1,2,...,n? b. Based on your answer in (a), find the maximum likelihood estimator of p.

Assume that the normal distribution can be used to approximate the following binomial distribution question. A survey of adults found that 6% say their favorite sport is auto racing. You randomly select 400 adults and ask them to name their favorite sport. Complete parts (a) and (b). (a) Find the probability that the number of people who say auto racing is their favorite sport is at most 30. (b) Find the probability that the number of people who say auto racing is their favorite sport is more than 33. (Round to four decimal places as needed.)

In a previous problem, we saw two distributions for triathlon times: N(u = 4313; o = 583) for Men, Ages 30 - and N(u = 5261; o = 807) for the Women, Ages 25 - 29 group. Times are listed in seconds. Use this information to compute each of the following: 34 a) The cutoff time for the fastest 5% of athletes in the men's group, i.e. those who took the shortest 5% of time to finish. seconds (Round to the nearest second.) b) The cutoff time for the slowest 10% of athletes in the women's group. seconds (Round to the nearest second.)
