The weights of a large number of miniature poodles are approximately normally distributed with a mean of 8 kilograms and a standard deviation of 0.7 kilogram. If measurements are recorded to the nearest tenth of a kilogram, find the proportion of these poodles with weights (a) over 8.9 kilograms; (b) of at most 8.6 kilograms; (c) between 7.4 and 9.1 kilograms inclusive.
