PLEASE HELP BEEN STUCK FOR HOURS WILL MARK THE BRAINLIEST<br> HAVE TO ANSWER A,B, and C
zaharov [31]

Answer:

A. 1)5.5 2)4.5 3)5.75 4)6.25 B. 1.75 C. A correct B incorrect C incorrect D correct

Step-by-step explanation:

Mean is a fancy way of saying <em><u>Average </u></em>, when calculating average you add all the numbers and divide by how many numbers there are:

<em><u>A</u></em>

<u>1.</u>

8+6+3+5=22/4=5.5

<u>2.</u>

5+7+4+2=18/4=4.5

<u>3.</u>

8+7+5+3=23/4=5.75

<u>4.</u>

6+8+4+5=25/4=6.25

<em><u>B</u></em>

largest mean is 6.25, smallest mean is 4.5:

<u>Subtract lowest mean from highest mean:</u>

6.25-4.5=1.75

<em><u>C</u></em>

<u>A)</u>

this is correct because averaging your average gives an overall average,

<u>B)</u>

if a is correct b has to be incorrect

<u>C)</u>

if D is correct C must be incorrect

<u>D)</u>

The closer they are together, that means more likely to be accurate because they are almost the same

I hope this helps u!

pls pls PLS give a brainliest and a thx ;)
