(Find Normal Proportions)

The lengths of Atlantic croaker fish are normally distributed with μ = 10 inches and σ = 2 inches.

a) Draw the distribution of fish lengths above the axis, and label the mean (which I believe is μ=10).

b)Gently shade an area on the graph that is equal to the proportion (or percentage) of croaker fish that are between 7 and 15 inches long.

c) Draw the standard normal distribution, label the axis, locate both z-scores on the axis (z7 = -1.5, z15 = 2.5), and shade an area equal to the probability that a randomly chosen croaker fish will be b/t 7 and 15 inches.
