Answer 1

1) for the given table P[PERSOn is male = P(Male) = 565 Looo (given) 545 Looo P[Person has master degree )P(Master) = (given) Therefore, PIA person is male or has a master degree) = Pemale U Master) = P(Male) + PC Master) - P(Maten Master) - (I) Also, P (Malen Master) = 225 Looo (given) Putting values in eqncis, SOS Looo + P(Male & Master) = 545 1000 225 LOOG aas 1000 2) = 650 Hence, required probability = 0.885 We have Ist quartile Q, = 400 3rd quartile de = The Inter-quartile range = @3-d, = 250 upperlimit = dz + 1.5(250) = 650+ 375 = 1025 Lower limit= 0,- 1.5(250) = 25
