Will get ! the safety manager at bumbler enterprises provides the graph to the right and he claims that the rate of worker injuries has been reduced by 50% over a 12 year period. does the graph support his claim? explain. a. the graph does not support his claim. the vertical scale is different for each bar. b. the graph does not support his claim. the vertical scale does not start at 0 which distorts the percent of change. c. the graph does not support his claim. the vertical tick marks are too far apart to determine the exact value for the proportions. d. the graph supports his claim. the height of the bar for 2004 is less than or equal to 50% of the height of the bar for 1992.
