For a sample of measurements x-bar = 10m, median = 13m standard deviation = 4m and sample variance = 16m^2
a) if the data is changed to centimeters (i.e. yi=100xi) then find the new set of measurements
Here, I just multiplied all of the above answers by 100, and assumed that that was correct BUT, if I use that logic for part b, it starts to get confusing...
b) IF the data is transformed to yi=(xi-10)/4 find the new measurements
... if I try to do the same thing (sub the x measurements into the new formula) I end up with an average length of 0, which makes no sense to me, and makes me think that I must be doing something wrong!!
If you know how to solve this, that would be fantastic!
