For the normal approximation to the binomial distribution with n = 100 and p = 1/5, the probability of selecting a score greater than or equal to 25 is p = 0.1056.
 
  Indicate whether the statement is true or false

Question 2

Which of the following accurately describes the chi-square distribution?
 
  A) symmetrical with a mean of zero
  B) positively skewed with all values greater than or equal to zero
  C) negatively skewed with all values greater than or equal to zero
  D) symmetrical with a mean equal to n - 1

Question 3

For the normal approximation to the binomial distribution with n = 100 and p = 1/2, a score of X = 60 corresponds to a z-score of z = 2.00.
 
  Indicate whether the statement is true or false

Question 4

How does the difference between fe and fo influence the outcome of a chi-square test?
 
  A) the larger the difference, the larger the value of chi-square, and the greater the likelihood of rejecting the null hypothesis
  B) the larger the difference, the larger the value of chi-square, and the lower the likelihood of rejecting the null hypothesis
  C) the larger the difference, the smaller the value of chi-square, and the greater the likelihood of rejecting the null hypothesis
  D) the larger the difference, the smaller the value of chi-square, and the lower the likelihood of rejecting the null hypothesis
