HELP ME SOMEBODY PLEASE

Answer 4

First, calulate the mean: m1= (8 + 6 + 9 + 12 + 19 + 7 + 10 + 8)/8.
Then remove the outlier (19)
Now calculate the mean again: m2= (8 + 6 + 9 + 12 + 7 + 10 + 8)/7.

If you then calculate m1-m2, you've found the difference.

Answer 5

is it 0.6?

Answer 7

No, I've got another result.

What results did you get for both means?

Answer 8

72 and 372

Answer 9

Both are wrong. m1 = (8 + 6 + 9 + 12 + 19 + 7 + 10 + 8)/8.

So: add up all the number, then divide by 8. You may use your calculator!

Answer 10

79/8 @ZeHanz

Answer 11

=9.875 OK, just write it as a decimal number. The answer options are also.

Answer 12

What is your outcome of m2 = (8 + 6 + 9 + 12 + 7 + 10 + 8)/7 ?

Answer 13

60/7 @ZeHanz
