Answer #1

Given that a population N=9 has a mean of µ=21.

Now that one score is changed from X=14 to X=32, now we need to find the value for the new mean.

We know that,

[Now one score is changed from X=14 to X=32 so we subtract 14 from the total and add 32 to the total.]

Hence the value for the new mean is 23
