Question 1 A random sample of middle-aged healthy women was selected and their bone (femur) densities (g/cm²) were measured. The results were: 0.70 0.83 0.92 0.72 0.73 0.75 0.75 0.76 0.83

0.84 0.84 0.86 0.87 0.93 0.95 0.96 0.97 1.00 0.79 0.88 1.01 0.80 0.82 0.89 0.91 1.02 1.08 0.82 0.91 1.09 a) What is the data type? b) Why is data type important? c) What is the importance of a random sample. Explain your answer. d) Prepare a frequency distribution of bone density. Use classes of width 0.05 and the first class should be ≥ 0.70 and <0.75. e) Construct a cumulative frequency distribution of bone density. f) Construct a relative frequency distribution of bone density. g) Comment on the frequency distribution. h) Construct a histogram for bone densities.
