Given X = 0.85Y, Y = 0.89X, σ_x = 3, r will be

The regression lines cut each other at the point of

How many combinations may be made of 10 things taken 4 at a time?

Probability limit can be

Suppose, it is calculated that 'a' is 4 and 'b' is 2 for a particular estimating line with one independent Variable. If the independent variable has a value of 5, what value should be expected for the dependent variable?

Three numbers an selected at random without replacement from the set of the numbers [1, 2, . . . ., N]. The conditional probability that the third number lies between the first two numbers if the first number is known to be smaller than the second is

Statement I A hypothesis test for comparing the variances of two independent populations with the help of variances of two small samples is known as chi-square test.
Statement II To test the hypothesis that the population standard deviation has a specific value on the basis of the values of sample standard deviation of small sized sample, F-test isrelevant.

Given

What will be at 'A' point?
