**9. Find the z-scores that cut off the middle 90% of the graph from the two tails.**The graph is a standard normal distribution curve (bell curve). The shaded area represents the middle 90% of the distribution. The z-scores on the x-axis mark the boundaries of this central region, indicating where the tails (outer 5% on each side) begin.**10. Find the z-scores that cut off the middle 80% of the graph from the two tails.**This graph is also a standard normal distribution curve. The shaded region now covers the middle 80% of the graph. The z-scores on the x-axis denote where the tails (outer 10% divided equally on each side) start.
