SECTION-B
UNIT-I
9. Compare various sampling techniques.
10. In a trip organized by a college there were 80 persons, each of whom paid Rs. 15.5 on an
average. There were 60 students each of whom paid Rs. 16. Members of teaching staff
were charged at higher rate. The number of servants were 6 (all males) and they were not
charged anything. The number of ladies was 20% of the total of which one was lady staff
member. Tabulate this information and calculate total contribution as well as contribution
of staff per head.
UNIT-II
11. In a random sample of 1,200 persons from town A, 600 are found to be consumers of
wheat. In a sample of 1,000 from town B, 600 are found to be consumers of wheat. Do
these data reveal a significant difference between town A and town B, so far as the
proportion of wheat consumption is concerned?
12. Discuss hypothesis testing in details.
UNIT-III
13. Calculate the correlation coefficient from the following data of marks obtained in physics
(X) and chemistry (Y) :
X 49 60 58 47 49 33 65 43 46 67
Y 47 65 50 48 55 58 63 48 50 69
