The difference is 1.74
Step-by-step explanation:
This question is the continuation to a question I already answered.
So, I will pick my answers from there
[tex]\bar x_{Red} = 15.11[/tex]
[tex]\bar x_{Blue} = 16.85[/tex]
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)
[tex]d = |\bar x_{Blue} -\bar x_{Red} |[/tex]
This gives:
[tex]d = |16.85 - 15.11|[/tex]
[tex]d = |1.74 |[/tex]
Take absolute value of 1.74
[tex]d = 1.74[/tex]
