3. Using a default dictionary constructed as a list, create an indexed version of the twelve months organized by their first letter.

Plot two random number distributions of 10 numbers each along with their statistical mean. The first distribution should have a mean value of 5 and a standard deviation value of 2 while the second distribution a mean value of 3 and a standard deviation value of 5. For a successful plot function make sure the 4. Plot two random number distributions of 10 numbers each along with their statistical mean. The first distribution should have a mean value of 5 and a standard deviation value of 2 while the second distribution a mean value of 3 and a standard deviation value of 5. For a successful plot function make sure the mean values are lists with the same number of values as their corresponding distributions
