can you help figure out how to solve this?,i understand the basic equation for variance, but in my calculations, somthing is coming up wrong, but I have no idea how to slove for zcore yet alone Chebyshev's theorem, my teacher barely explained it, and my book is no help.
the numbers for variance are 450,300,400,500,400
Zscore=Consider a sample with data values of 10, 20, 12, 17, and 16
Chebyshev's theorem=consider a sample with a mean of 30 and a standard deviation of 5.
# 20 to 40, at least %
# 15 to 45, at least %
# 22 to 38, at least %
# 18 to 42, at least %
# 12 to 48, at least %
