A random sample of size 64 was taken from a population that is right-skewed with a mean of 78 and standard deviation of 8. The document asks to (a) describe the sampling distribution of x, (b) find the probability that x is greater than 79.15, (c) find the probability that x is greater than 75.7, and (d) find the probability that x is between 76.85 and 80.1.
