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.

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.
