In the sample has a mean of m=90 and each score in the sample is multiply by 5 and you want to calculate the mean for the new distribution, you only have to multiply the mean (m=90) by 5.
Then:
m= 90x5 m=450
Therefore, the answer is: The <span>mean for the new distribution is 450 (m=450).</span>
the first blank is 82, the second blank is 8,910. I got that third blank wrong and it should be 7.1 I think. and the last block is should not. to find the third box all you need to do is:
82+990=1,072 then divide 82 by 1,072 and round to the nearest tenth
