In the list of five measurements shown below, one is blurred. What must this value be, if the mean of the five measurements is 6? 8 5 10 3 #.

Answer 1

6 * 5 = 30

What number is missing?

Answer 2

Hi Ms. Sue. That is what I'm guessing I have to figure out. They say the median is 6. so out of 8 5 10 3 # I have to figure out what this (#) value is? I don't know if I should do the five number summary and box plot or just box plot??????

Answer 3

Do it whatever way your teacher wants.

Did you get the missing number for the mean?

Answer 4

no, I'm struggling with how to figure that out. That's where I am stuck

Answer 5

(8+5+10+3+x)/5 = 6

Answer 6

AWESOME! I put 6 in between 3 5 6 8 10 but I thought that was too simple.

Answer 7

It's not 6, Renee. You have to solve for x in the equation I made for you.
(8+5+10+3+x)/5=6
(26+x)/5=6
26+x=30
x=?

Answer 8

I got it finally. x=4
