Students applying for admission to a Master's program in statistics must submit scores from the GRE test, which includes a verbal and a quantitative component. Shown here are the scores for 100 applicants to a particular Master's statistics program. The numbers in parentheses are the expected values if the verbal scores and quantitative scores are independent.
We wish to test whether quantitative scores are associated with verbal scores. Choose the statement that is true about the hypothesis test or state that all of the statements are false.
◦ The chi-square test is not appropriate because some expected cell counts are less than 5.
◦ All of these statements are false.
◦ A hypothesis test cannot be conducted on these data because one of the observed cell counts is zero and there must be at least one observation in each cell.
◦ The sample size is large so the chi-square test is appropriate.
