Click here to view page 1 of the standard normal distribution table Click here to view page 2 of the standard normal distribution table Using the correlation coefficient of the normal probability plot, is it reasonable to conclude that the population is normally distributed? Select the correct choice below and fill in the answer boxes within your choice (Round to three decimal places as needed.) O A No. The correlation between the expected 2-scores and the observed data, does not exceed the critical value. Therefore, it is reasonable to conclude that the data come from a normal population OB. No. The correlation between the expected 2-scores and the observed data, does not exceed the critical value . Therefore, it is not reasonable to conclude that the data come from a normal population OC. Yes. The correlation between the expected 2-scores and the observed data exceeds the critical value. Therefore, it is reasonable to conclude that the data come from a normal population. for Suce OD. Yes. The correlation between the expected 2-scores and the observed data, exceeds the critical value. Therefore, it is not reasonable to conclude that the data come from a normal population or Suce

Correlation between z-score and observed data = 0.996

Critical correlation value for n = 16 is 0.941

Yes, the correlation between expected z-score and observed data, 0.996, exceed the critical value, 0.941. Therefore, it is reasonable to conclude that data come from a normal population.
