O A. Because the correlation between the expected z-scores and observed values is greater than the critical value, it is reasonable to conclude the data come from a population that is approximately normal.
O B. Because the correlation between the expected z-scores and observed values is less than the critical value, it is reasonable to conclude the data come from a population that is approximately normal.
O C. Because the correlation between the expected z-scores and observed values is less than the critical value, it is not reasonable to conclude the data come from a population that is approximately normal.
O D. Because the correlation between the expected z-scores and observed values is greater than the critical value, it is not reasonable to conclude the data come from a population that is approximately normal.
