For the following questions answer them individually
If a discrete random variable X follows uniform distribution and assumes only the values 8, 9, 11, 15, 18, 20, the value of $$P(\mid X - 14 \mid < 5)$$ will be:
The curve obtained by joining the points, whose x-coordinates are the upper limits of the class interval and y-coordinates are corresponding cumulativefrequencies is called:
The probability density function of a random variable X is $$f(x) = \frac{\pi}{10} \sin \frac{\pi x}{5}; 0 \leq x \leq 5$$. The first quartile of X is:
60% of the employees of a companyare college graduates. Of these, 10% are in sales. Of the employees who did not graduate from college, 80% are in sales. The probability that an employee selected at randomisin sales, is:
If $$r_{12} = +0.80, r_{13} = -0.40$$ and $$r_{23} = -0.56$$, then the square of multiple correlation coefficient (correct to four decimal places) $$R^2_{1.23}$$ is equal to:
If the multiple correlation coefficient of $$X_1$$, on $$X_2$$, and $$X_3$$ is zero, then:
