a) Mean Calculation:   Mean = 4.1

b) Determining Mode: There will be two modes:  3 and 4

c) Determining Median: Median= 3.5

d) Determining Range: The range is 11

Step-by-step explanation:

The Table for Freddy's Miles:

Date               Miles

24-Sep              2

25-Sep             5

26-Sep             4

 27-Sep             1

28-Sep              3

29-Sep              12

30-Sep               4

1-Oct                   3

2-Oct                  3

3-Oct                  4

a) Mean Calculation:

As the miles data is shown as:

                                                 2, 5, 4, 1, 3, 12, 4, 3, 3, 4

Adding up all the numbers and then dividing the sum by the total number of values would give us the mean value:

Mean = [tex]Mean = \frac{2 + 5 + 4 + 1 + 3 + 12 + 4 + 3 + 3 + 4}{10}[/tex]

          [tex]= \frac{41}{10}[/tex]

           = 4.1

b) Determining Mode:

As the miles data is shown as:

                                                 2, 5, 4, 1, 3, 12, 4, 3, 3, 4

Putting the number in order:

                                                 1, 2, 3, 3, 3, 4, 4, 4, 5, 12

As it is clear than 3 appears three times, as does 4.

Hence,  there will be two modes:  3 and 4

c) Determining Median:

As the miles data is shown as:

                                                 2, 5, 4, 1, 3, 12, 4, 3, 3, 4

Putting the number in a order (from smallest to the largest):

                                                 1, 2, 3, 3, 3, 4, 4, 4, 5, 12

As the total number of items in the given data is an even number, we must have to take the mean of the two middle numbers:

                                            1, 2, 3, 3, 3, 4, 4, 4, 5, 12

Median = The average of two middle numbers or values ÷ 2

             = [tex]Median = \frac{3+4}{2}[/tex]

            = 3.5

d) Determining Range:

As the miles data is shown as:

                                                 2, 5, 4, 1, 3, 12, 4, 3, 3, 4

Putting the number in a order (from smallest to the largest):

                                                 1, 2, 3, 3, 3, 4, 4, 4, 5, 12

The maximum value = 12

The minimum value = 1

Range = maximum value - minimum value

           = 12 - 1

            = 11
