Answer:
The mean of the set of scores is 22.75
Step-by-step explanation:
WHY?
In a homework given to 12 students, the following scores were recorded:
18, 29, 18, 32, 22, 21, 22, 18, 27, 26, 18, 22.
What is the mean of the set of scores?
Add the twelve scores
18+29+18+32+22+21+22+18+27+26+18+22
= 273
then the answer by adding the twelve scores is 273. Then the next step is that the answer of the adding twelve score of a student is 273 devide it to 12 because the number of a student is twelve.
273 divided by 12 is equal to 22.75
so the mean of it is 22.75
thats it thanks...
