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.)
A. No. The correlation between the expected z-scores and the observed data,
conclude that the data come from a normal population.
does not exceed the critical value,
Therefore, it is reasonable to
O B. No. The correlation between the expected z-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.
O C. Yes. The correlation between the expected z-scores and the observed data,
exceeds the critical value,
Therefore, it is reasonable to conclude that
the data come from a normal population.
O D. Yes. The correlation between the expected z-scores and the observed data,
exceeds the critical value,
Therefore, it is not reasonable to conclude
that the data come from a normal population.
