16,19,18,19,9 Find the mean and median of the numbers. Round answers to the nearest tenth.

The mean is 16.2
The median is 18

For mean you have to add all numbers and then divide by how many numbers they are in this case they were 5 numbers so divide by 5 after adding them up

For median, it’s the middle number so the number in the middle is 18

If i think this is what your asking, he should look at the grams or pounds/ounces and compare the to their cost then max can identify which one is proportional and which is not ( i think xd)
