Select the correct answer from the following options:

The point of intersection of the two regression lines is:

If the arithmetic mean and geometric mean of two numbers are 36 and 30 respectively, then their harmonic mean is:

The type of survey where every unit of the population is enumerated is called:

A student discovers that his grade on a recent test was the \(72^{\text{nd}}\) percentile. If 90 students wrote the test, then approximate number of students who received a higher grade than he did are:

If the mean and variance of a binomial distribution are 10 and 5 respectively, then the value of \(p\) is:

If A and B are independent events, then:

If regression line of X on Y is linear, then the regression line of Y on X is:

A, B, and C are three mutually exclusive and exhaustive events associated with a random experiment. Also, \(P(B) = \frac{3{2} P(A)\) and \(P(C) = \frac{1}{2} P(B)\), then \(P(A)\) is:}

X speaks truth 4 out of 5 times. A die is tossed and X reports it to be 6. The probability that there was actually 6 is:

If the regression coefficient of X on Y is \(b_{xy}\), and the variables are transformed as \(U = \frac{X - a}{h}\), \(V = \frac{Y - b}{k}\), then the regression coefficient of U on V is:

If \(P(A) = \frac{1{2}\), \(P(B) = \frac{1}{3}\), and \(P(A \cap B) = \frac{1}{6}\), then \(P(A \cup B)\) is:}

If A and B are two events, then \(P(A|B)\) is:

In case of Simple Random Sampling with Replacement, the sample mean:

If \(X\) follows a uniform distribution on \([0, 1]\), then the variance of \(X\) is:

If A and B are mutually exclusive events, then:

The range of Coefficient of Variation (CV) is:

The sum of absolute deviations is minimum when taken from:

Let the Arithmetic Mean of \(n\) observations be AM. If 5 is added to all the observations, then the new AM will be:
