Some variable of interest follows a(normal/right-skewed)distribution with a mean of 100 and a standard deviation of 10. In a random sample ofsize(5/50), what is the probability that the sample mean is between 95 and 120?
In which of the following situations (select more than one if needed) is it possible to calculate the probability and would the calculated probability be exact or approximate?

E) | right-skewed, 5, and exact | |
F) | right-skewed, 5, and approximate | |
G) | right-skewed, 50, and exact | |
H) | right-skewed, 50, and approximate | |
