Correct for plato users:)

Answer 2

The difference is 1.74

Explanation:

This question is the continuation to a question I already answered.

So, I will pick my answers from there

`\bar x_(Red) = 15.11`

`\bar x_(Blue) = 16.85`

See comment for link to that solution

Required

The difference between those who purchase both

Since the average of both colors have been given;

Next, we simply calculate their difference (d)

`d = |\bar x_(Blue) -\bar x_(Red) |`

This gives:

`d = |16.85 - 15.11|`

`d = |1.74 |`

Take absolute value of 1.74

`d = 1.74`
