ANSWER:

Solution:

Step 1 of 3:

Here,the frequency distribution of ages of residents of Medicine lake is given.

We need to find the mean of the frequency distribution.

The frequency distribution given is

                         Age

                     Frequency

                        0-9

                            30

                       10-19

                            28

                       20-29

                            17

                       30-39

                            22

                       40-49

                            23

                       50-59

                            46

                       60-69

                            37

                       70-79

                            18
