Question

Suppose a sample of O-rings was obtained and the wall thickness (in inches) of each was recorded Use a normal probability plot to se assess whether the sample data could have come from a population that is normally distributed Could the population be normally dstributed? zes A. Yes, since the relationship between the expected z-values and the observed values is not linear O B. No, since the relationship between the expected z-values and the observed values is approximately linear c. Yes, since the relationship between te expeded z-values and the observed values is approximately linear O D. No, since the relationship between the expected z-values and the observed values is not linear Seb Is cha useCick to seledt your answer

Explanation / Answer

Data not given

C or D option is right

Since data is not given, make the plot and if it is a linear line then option C is correct otherwise D

Normal Probability Plot. The normal probability plot (Chambers et al., 1983) is a graphical technique for assessing whether or not a data set is approximately normally distributed. The data are plotted against a theoretical normal distribution in such a way that the points should form an approximate straight line.
