Number of hip fractures in menopausal women is currently a casue for concern in orthopedic research today. One study focusing on these events followed a group of 1,700 women for 15 years and sorted out the number of fractures by how many women experienced them. The following table summarizes their results. number of fractures 1 2 3 4 total patients 789 524 211 176 1.what proportion of women had two or more fractures? 2. what is the expected value for the number of fractures seen in this study? (round to the nearest whole fracture). 3. what is the variance of this distribution.
