SOMEONE HELP ME AND CHECK MY WORK!!!
Find the mean varience and standard deviation for the following data set
49,32,35,43,45,40,53,55,42
mean: 43.7…
vairence 59.194…
deviation 7.2537772195331
Got the same.
For your mean, should have rounded to 43.8 in with 1 decimal place
I noticed that you divided by 8 to the the variance, but
you divided by 9 to get the SD.
Is that what your text told you to do?
I would have expected them to be consistent.
The results are correct following that process
