A group project estimates that thirty percent of students will
do problem A in an assignment. Assume the class has four
hundred
students in total, each of these student has 0.3 probability of
doing problem A. Find the probability if there are at least
one
hundred and thirty five students will do problem A. Use either the
normal or Poisson approximation.
Justify your choice of approximation.
The solution to this problem is given below

Need 9-12, 19 answered please!! (9-12) Thirty-seven (37%) percent of students who major in Kinesiology do not work to subsidize their education whereas 45% of these students work at Bill Miller making $7.75 an hour and the remaining students work at West Telemarketing making $11.25 an hour. Let X be the hourly income of Kinesiology majors with the following probability distribution given by p(x) What is the mean hourly wage for this population of Kinesiology students? (rounded) o. What is...

(A) [10 points) What is the probability that the selected person is a democrat? (B) (10 points] If the person selected is found to be a democrat, what is the probability that this person is male? (C) (10 points) What is the probability that the person selected is a female democrat?...
4. For the following problem, ignore the year of birth while comparing two birthdays. Moreover, assume that the year is exactly 365 days (ignore the 29th of February) Note that matching birthdays means the birthdays are the same (a) You are a member of a class room that has n +1 students including you. What is the probability that you find at least one student, other than you, who has a birthday that matches yours? (b) In another classroom that...

QUESTION 3 Your statistics professor has developed the rather annoying habit of asking students in your class to solve one homework problem that was assigned at the start of class. She randomly picks the student using names in a hat. You and 3 of your friends stay up to watch the baseball playoffs of both the AL and NL and have a very late night and a resulting late morning where none of you got a chance to do the...
