Suppose we have taken a sample of size 14 from a population that is normally distributed with population variance 12. We find that the sample mean is 80, and the sample variance is 10. Calculate the value of x based on the formula for the sampling distribution of S2. Round your answer to decimals. Find the probability that the sample variance is greater than 10. Round your answer to 4 decimals.
