The weights of a large number of miniature poodles are approximately normally distributed with a mean of 9 kilograms and a standard deviation of 0.9 kilogram. If measurements are recorded to the nearest tenth of a kilogram, find the proportion of these poodles with weights:

(a) over 10.3 kilograms; (b) of at most 9.5 kilograms; (c) between 8.3 and 10.4 kilograms inclusive. Answer : Given : The population mean $(μ) = 9$ The population standard deviation $(σ) = 0.9$ Solution : a) The probability that…
