5. Find the mean of the data set
283, 351, 131, 235, 298, 192, 341, 306, 261
A. 283
B. 272
C. 259
D. 266

D. 266

Step-by-step explanation:

I want to start off first by giving the definition of "mean". A mean is the average of the set of data given. To do this one must add the data all together. HOWEVER (this is important)! Once you added the data you must divide the sum by the number of data there is given.

So the problem we are given is to find the mean of the data set : 283, 351, 131, 235, 298, 192, 341, 306, 261

Step 1:

283+351+131+235+298+192+341+306+261 = sum of the data set

283+351+131+235+298+192+341+306+261 = sum of the data set

1000+298+192+341+306+261 = sum of the data set

1000+831+306+261 = sum of the data set

1000+831+567 = sum of the data set

1000+1398 = sum of the data set

2398 = sum of the data set

mean =

mean= 266.44...

For the answers, there is no 266.44... choice, but the closest answer we have that is similar to what the answer we got is D. 266.

Its 266.

Step-by-step explanation:

You gotta add 283 + 351 + 131 + 235 + 298 + 192 + 341 + 306 + 261

and it equals 2398.

then do 2398 divided by 9

and that equals 266.444...(you know what I mean cuz)

And round it off to 266.
