Data were collected on a sample of 500 business students and the mean number of course credits taken was 18. how many course credits did the total sample take collectively?

Collectively, the total sample took 9000 course credits.

Step-by-step explanation:

The mean number of course credits taken is the total number of credits which the sample took collectively divided by the size of sample. Mathematically

In which

M is the mean number of course credits taken

T is the total number of course credits taken

N is the size of the sample.

In this problem, we have that:

We have to find T. So

Collectively, the total sample took 9000 course credits.

no not all of them.

step-by-step explanation:

some of them have a square base.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
