Fill in the blank(s) with correct word Q. 2 A sample of size 200 is taken at random from an infinite population. Given that the population proportion is 0.60, the probability that the sample proportion is greater than 0.58 is: a. 0.281 b. 0.719 c. 0.580 d. 0.762 Q. 3 For a regression analysis to be valid, the error variable must have a mean of ____________________. Fill in the blank(s) with correct word Q. 4 Given a binomial distribution with n trials and probability p of a success on any trial, a conventional rule of thumb is that the normal distribution will provide an adequate approximation of the binomial distribution if a. np 5 and n(1  p) 5 b. np 5 and np(1  p) 5 c. np 5 and n(1  p) 5 d. None of these choices. Q. 5 For a regression analysis to be valid, the error variable must have a(n) ____________________ distribution. Fill in the blank(s) with correct word Q. 6 As a general rule, the normal distribution is used to approximate the sampling distribution of the sample proportion only if: a. the sample size n is greater than 30. b. the population proportion p is close to 0.50. c. the underlying population is normal. d. np and n(1  p) are both greater than or equal to 5.
