A group of 894 women aged 70 – 79 had their height and weight measured. The mean height was 159 cm with a standard deviation of 5 cm and the mean weight was 65.9 kg with a standard deviation of 12.7 kg. Both sets of data are fairly normal. a) Sketch a normal curve to represent the heights. Determine the percentage of the population that is expected to be taller than 166 cm. b) Sketch a normal curve to represent the weights. Determine the percentage of the population that is expected to weigh between 55 and 75 kg.
