syntacus:
Did anyone do the scaling one? ( The first question in part B )
And also the last question in part A.
The assumed mean was 299. something right? and the s.d 0.49?
What was to be done in the second part of the question? I just multiplied both the answers by 1000 to get the ans in the thing that was required:/ others did something else though.. dunno.
Also in the true and false question.. I got 2 Trues and 4 False... what about you guys?
DrEvil:
I also multiplied with 1000 but its wrong as said by most of the ppl... :( :( :(
well i got 3 trues and 3 false but most of the ppl got 2 trues and 4 false... :(
