According to the textbook, let's assume that the mean weight of one-year girls in the UK is normally distributed with a mean of about 9.5kg with a standard deviation of approximately 1.1kg. Please estimate the percentage of one-year old girls in the UK that meet the following conditions, without using a calculator. Draw a sketch and shade the proper region for each problem.  - less than 8.4kg - between 7.3kg and 11.7 kg - more than 12.8kg
