Question:
Consider the normal curve in the figure to the right, which illustrates the relative frequencies in a distribution of systolic blood pressures for a sample of female students. The distribution has a standard deviation of 14. | 90105120135150165Bloodpressure A graph with a horizontal axis labeled "Blood pressure" from less than 85 to 165 plus in increments of 5 and an unlabeled vertical axis contains a normal distribution curve. The curve is close to the horizontal axis near the left edge of the graph and then rises from left to right at an increasing and then decreasing rate to its peak about halfway between the bottom and top of the graph at approximate horizontal coordinate 125. The curve then falls from left to right at an increasing and then decreasing rate, approaching the horizontal axis at the right edge of the graph. |
