1.Explain why X DOES NOT have a binomial distribution in each of the situations below. (Hint, check the criteria; if you find one that isn't met, X isn't binomial.)

a.Suppose a police officer takes a two-hour time period and records the number of vehicles traveling on US 131 that exceed the speed limit (where the speed limit is 70 miles per hour). Let X denote the number of vehicles that were exceeding the limit.

A:

b.Suppose 10% of OSU business students major in international marketing. You keep sampling students at random from our class until you find someone who is majoring in international marketing. Let X = the number of students you have to sample.

A:

c.You have 10 people working for you, 5 men and 5 women, and you have to choose different people be on a committee that no one wants to be on. You put their names into a hat and pull out 3 names, one by one. Let X = number of women who end up on the committee.

A:

d.You take a random sample of 10 college students from stat 1430 and record their status (freshman, sophomore, etc.).

A:

e.Suppose a police officer takes a two-hour time period and records the number of vehicles traveling on US 131 that exceed the speed limit (where the speed limit is 70 miles per hour). Let X denote the number of vehicles that were exceeding the limit. Explain why X does NOT have a binomial distribution.
