A random sample of 60 business students required an average of 50.7 minutes to complete a statistics exam. Assume that the population standard deviation to complete the exam was 10.4 minutes.
 
  The standard error of the mean for this sample is ________.A) 0.63
  B) 1.07
  C) 1.34
  D) 2.30

Question 2

Consider the partially completed randomized block ANOVA summary table.
 
  Source Sum of
  Squares Degrees of
  Freedom Mean Sum of
  Squares
  F
  Between 600 3
  Block 5
  Error 750
  Total 2,150 23
 
  Using  = 0.05, the conclusion for this ANOVA procedure would be that because the main factor test statistic is ___________________ ___________________ ___________________ _______.
  A) more than the critical value, we cannot reject the null hypothesis and conclude that there is a difference in population means
  B) less than the critical value, we can reject the null hypothesis and conclude that there is no difference in population means
  C) less than the critical value, we cannot reject the null hypothesis and conclude that there is a difference in population means
  D) more than the critical value, we can reject the null hypothesis and conclude that there is a difference in population means
