how'd the k - 125 change to 125 - k???P(k-125/4.2 <Z< 128-125/4.2) =.7465
Fi(3/4.2) - fi(k-125/4.2) = .7465
fi(k-125/4.2) = .0158
since its lower than .5,
1-fi(125-K/4.2) = .0158
.9842 = fi(125-K/4.2)
Using normal table:
2.15 = 125-k/4.2
9.03 = 125-K
K = 115.97 = 116
Apparently, the mark scheme is wrong.now ,......how to know class boundaries here???
question says less than 45....less than 50.............bt ms writes this Class as 45-50 widout paying attention to the damn inequality signs............now why the hell were they there/....if we dun have to use them.....m cnfused.....is there any rule to detrmine class widths
