For a normally distributed population, mean of 6.5 and standard deviation of 4, compute:

The probability of picking one item from the population and having it fall between 6.5 and 14.5.

The probability of picking one item and have it be above 14.34.

The point if the probability of picking an item from the population and having it fall above the point is 2.5%.

Two points, equidistant from the mean, one to the left of the mean and one to the right that will include 98.98% of the population.
