Given the sample space:
ΩΞ
= {a,b,c,d,e,f}
and events:
{a,b,e,f}
A = {a, b, c, d}, B = {c, d, e, f}, and C = {a, b, e, f}
For parts a-c: determine the outcomes in each of the provided sets. Use proper set
notation.

If the outcomes in 2 are equally likely, calculate P(AN BNC).
Suppose a sample of O-rings was obtained and the wall thickness (in inches) of each
was recorded. Use a normal probability plot to assess whether the sample data could
have come from a population that is normally distributed.

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. 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.
