Of the 3800 students at a college, 280 are mature students. 50 students are selected at random from the 3800 students at the college and asked to participate in a survey.
 
  The questions in the survey relate to the students need for financial assistance. The random variable X represents the number of mature students in the sample. A) hypergeometric; N = 3800, n = 50, k = 280, x = 0, 1, 2, . . . , 50
  B) hypergeometric; N = 3800, n = 280, k = 50, x = 0, 1, 2, . . . , 50
  C) hypergeometric; N = 3800, n = 50, k = 280, x = 0, 1, 2, . . . , 280
  D) not hypergeometric

Question 2

Assuming that all conditions are met to approximate a binomial probability distribution with the standard normal distribution, then to compute P(x  23 ) from the binomial distribution we must compute as the normal approximation.
 
  A) P(x  23.5 ) B) P(x  23.5 ) C) P(x  22.9 ) D) P(x  23.1 )
