Question

2,3,2,3,3,5,5
give your answer as a fraction in its simplest form

Answer 1

Answer:

23/7

Step-by-step explanation:

Add all the numbers and divide by the amount of numbers added, 7.

Answer 2

Answer:

Adding the numbers up gives:

2 + 2 + 3 + 5 + 5 + 7 + 8 = 32

There are 7 values, so you divide

the total by 7:    32 ÷ 7 = 4.57...

So the mean is 4.57 (2 d.p.)
