Q.P. Code : 564165
Time : 3 hours Maximum : 75 marks
I. Essay ques. : (2 X 20 = 40)
ans any 2 ques..
1. a) Solve : XYP² + (X+Y)P +1 =0. (10) b) Before an increase in dosage of antibiotics on fish reared in a
research station, 400 out of 600 were in good health condition. After
an increase in dosage of antibiotics, 450 fish were in good condition
in a sample of 900 fish. Do you think that there has been any
significant increase in health condition of the fish after the increase
in dosage. (for Z(0.01) = 2.58 S.E). (10) 2. a) Integrate with respect to X: ex (1+sinx) (10) ----------------
1+cos x
b) 2 hundred individuals are classified to their eye and hair color
and we have the subsequent contingency table. Test whether the eye
and hair colors are independent. (for v=2, x² 0.05 =5.99). (10)

b) A simple random sample of size 400 has mean 25, the population
variance being 25. obtain an internal estimate of the population mean with
a confidence level of i) 99% and ii) 95%. If population variance is not
