You notice that the interval estimate for two values overlaps. what might this indicate?

This likely to infer that both of the points represents a genuine difference in the general population. Though one may absolutely have the same value in the general population, although one appears slightly higher, likely due to the variability of the sample.

Hello!

We can solve this problem using the Distributive Property, which states the following:

a(b + c) = ab + ac
a(b – c) = ab – ac

In this case, we’ll use the first of the two formulas. Insert any known values into the equation as follows:

a(b + c) = ab + ac
5(6x + 3y) = 5(6x) + 5(3y)

Now simplify the right side of the equation:

5(6x + 3y) = 30x + 15y

We have now proven the given expression to equal (30x + 15y).

Consequently, the correct answer is D.

I hope this helps!
