Qno.1
Let us complete the table as follows:
     
    Win
    Did not win
    Total
    Leading at half time
    352
    163
    515
    Not leading at half time
    178
    307
    485
     
    530
    470
    1000
a) Prob (Team wins) = 530/1000 = 0.530
b) Prob (Team leading at half time and team wins) = 352/1000 =0.353
c) Prob (Team wins/Team leading at half time) = 352/530 =0.664151
Qno.2
A/B = Company dominates category / company is a first mover
Since out of 80 companies that dominated, 59 are first movers
We can say P(B/A) = 59/80 =0.737
i.e. option iv is the answer.
b) In this case, we would select all first mover companies and find in them the dominates strategy kind.
i.e. instead of P(B/A) in a, here we would find P(A/B)
Qno.3
“The 90 minute Swedish Massage treatment gives a lift of 0.6 to the Facial care treatment”
Here after so much statistical calculations, inferences, estimations and predictions the above statement was released. Hence we can assume that this sampling analysis was done for large sample size and without bias.
From the conclusion we find that on an average the Swedish massage treatment if given for an average time of 90 minutes we can expect...
