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
0.2290.229	0.2290.229	0.2420.242	0.2470.247
0.2600.260	0.2550.255	0.2770.277	0.2810.281
0.2890.289	0.3060.306	0.3080.308	0.3410.341

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.
