The Virginia Cooperative Extension reports that the mean weight of yearling Angus steers is 1152 pounds and the standard deviation is 84 pounds.
Using N(1152, 84) for the Angus steers, what is the cutpoint data value where you would expect to find the highest 10% of weights?
REMEMBER: the Normal Distribution chart ONLY gives the area to the LEFT of a data value, you will need to subtract from 100 first!!!
First: What area are we looking for on the Normal Distribution Chart in order to find the top 10%?_______ Remember, the chart ONLY shows the area to the left.
Second: Use the blue table to find the area closest to our area. Look up the z-score.
What z-score corresponds to this area? _______
Third: What data value for steer weight corresponds to this z-score? _______
