Suppose a sample of​ O-rings was obtained and the wallthickness​ (in inches) of each was recorded. Use a normalprobability plot to assess whether the sample data could have comefrom a population that is normally distributed. | | 0.1580.158 | 0.1890.189 | 0.1950.195 | 0.2080.208 | |

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 answerboxes within your choice.
A. No. The correlation between the expected​ z-scores and theobserved​ data, _____ does not exceed does not exceed
the critical ​value, _______.​Therefore, it is not reasonable toconclude that the data come from a normal population.
B. Yes. The correlation between the expected​ z-scores and theobserved​ data, _______ exceeds the critical​ value, ______.​Therefore, it is reasonable to conclude that the data come from anormal population.
C. Yes. The correlation between the expected​ z-scores and theobserved​ data, _______ exceeds the critical value _____.​Therefore, it is not reasonable to conclude that the data comefrom a normal population.
D. No. The correlation between the expected​ z-scores and theobserved​ data, _______ does not exceed the critical​value, ______.​Therefore, it is reasonable to conclude that the data come from anormal population.
