Question from destinee, a student: please help me my problem is 5,11,19,3,15,17,5,n find n given the following info.range:16 mode:5 median:8 mean:10 what the heck is the answer |
Hi Destinee,
Look at the information given.
range: 16 --- The range of the 7 numbers given is 16 so this doesn't help much.
mode: 5 --- There are already 2 fives so this is not much help here.
median: 8 --- Not much help here either.
mean: 10 --- This looks promising. What is n is (5 + 11 + ... + 5 + n)/8 = 10?
Once you find n check to see if the range, mode and median are correct.
