The correct answer is A
For the study purpose, the mean of the observations is 148 gm and standard deviation is 17.4 gm. Approximately, the coefficient of variation equals to:
If the multiple correlation coefficient of X1 on X2 and X3 is zero, then:
The variance of degenerate random variable is:
A Poisson distribution has a double mode at x = 1 and x = 2. The probability for x = 1 or for x = 2 of these two values is:
Identify, from the following, the moment used as a measure of skewness?
For the random variable X with probability density function f(x) = (x−3)2 /5; x = 3, 4, 5, the variance of X is:

 X and Y are independent normal variables with mean 50 and 80 respectively and standard deviation as 4 and 3 respectively. What is the distribution o...
If the first, second and third moment about origin are 2, 8 and 14. respectively, then Karl Pearson gamma coefficient of skewness y1 is:
Let x and y be two variables with variance as 1990 and 796 with 11 and 9 number of observations respectively. The value of F(10, 8) at 5% level of sign...
