Time : 3 hours Maximum : 100 marks
ans any 5 ques..
All ques. carry equal marks.
(5 ? 20 = 100)
1. Explain the special features of central tendency.
2. The scores of 2 players A and Bin 12 rounds are provided below:
A 74 75 78 72 78 77 79 81 79 76 72 71
B 87 84 80 88 89 85 86 82 82 79 86 80
Identify the better player and the more consistent player.
3. From the subsequent data, obtain the association ranging from darkness of eye-colour in dad and son:
Fathers with dark eyes and Sons with dark eyes 1040
Fathers with dark eyes and sons with not dark eyes 160
dad with not dark eyes and sons with dark eyes 180
Fathers with not dark eyes and sons with not dark eyes 120
What would have been the frequency of fathers with dark eyes and sons with dark eyes of the identical total number had there been complete independence?
4. On the basis of observations made on 39 cotton plants, the total correlation of yield of cotton [ ], number of balls i.e., seed vessels [ ] and height of plants [ ] are obtained to be:
; ; .
calculate partial correlation ranging from yield of cotton and the number of balls eliminating the effect of height.
5. Describe the different steps involved in hypothesis testing.
6. Ten students are opted at random from a college and their heights are obtained to be 100, 104, 106, 110, 118, 120, 122, 124, 126, and 128 cms. In the light of these data, explain the
suggestions that the mean height of the students of the college is 110 cm.
The table value of t at 5% level for eight df is 2.306 and for nine df is 2.262 and 10 df is 2.228 for a two-tail test.
7. Three samples beneath have been found from population with equal variance. Test the hypothesis at 5% level that the population means are equal.
8 7 2
10 5 9
7 10 13
14 9 12
11 9 14
The table value of F at 5% for and is 3.88.
8. The subsequent data is collected on 2 characterizes :
Smokers Non-Smokers
Literate 83 57
Illiterate 45 68
Based on this can you say that there is no relation ranging from the habit of smoking and literacy.
9. What do you mean by reliability and validity of a measurement? define the different techniques available to assess every.
