7.S11 WP SS VS A random sample of 36 observations has been drawn from a normal distribution with mean 50 and standard deviation 12. Find the probability that the sample mean is in the interval 47 ≤ X ≤ 53. Is the assumption of normality important? Why? 7.S12 A manufacturer of semiconductor devices takes a ran- dom sample of 100 chips and tests them, classifying each
