A park ranger is studying the age and health of Black Cherry Trees in his park. Part of his study displayed the histogram below. Heights of Black Cherry Trees Frequency ОТ 8 60 65 70 75 80 85 90 Height (feet) Do not worry about the difference between class limits and class boundaries for this example. Just uses classes 60- 65, 65-70, 70-75 etc. 1. Construct a grouped frequency distribution for this data including relative, cumulative, and relative cumulative frequency. 2. Draw a frequency polygon for the data. 3. Draw an ogive for the data. Be sure to label the axis and use appropriate scales. If done using paper and pencil please use a ruler to be accurate.

Find the area of the shaded region. The graph to the right depicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15. A graph with a bell-shaped curve, divided into 3 regions by 2 lines from top to bottom, one on the left side and one on the right side. The region between the lines is shaded. Moving from left to right, the x-axis below the first line is labeled 75. The x-axis below the second line is labeled 110.

David and Patrick are playing baseball for the Cafe Tropical team. Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 250 feet and a standard deviation of 50 feet. If X = distance in feet for a fly ball, then X ~ N ( , ) If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled less than 220 feet? Sketch the graph. Scale the horizontal axis X. Shade the region corresponding to the probability. Find the probability. P = Find the 80th percentile of the distribution of fly balls. 80th Percentile: feet
