Q.4
Write any one long answer of the question?

On the assumption that IQ's one normally distributed. In the population with mean of 100 and standard deviation 15 what percentage of cases fall
Above 135 IQ
Above 120 IQ
Below 90 IQ
Between 75 and 125 IQ
14
OR

Suppose there one two independent samples. A and B with 4 and 5 cases. We have to establish that both sample have been drawn from the same population. (Apply Mann Whitney test): score of sample A and B.
Q.5
