his is not exponential equation, it is a straight line y = a + bx

The normal equations is

Using the table, putting these values in normal

Let U = F (x), then the distribution function of G of U is given by

Since F is non-increasing and its continuous.

G (u) =F (F ^-1 (u) ) implies G (u) =u

Then the p. d. f is

Since F is a distribution function takes value in range [0,1]. Hence

This is a uniform distribution on [

Let X ₁, X ₂, …, X ₁₂ be a random sample from a normal N (µ ₁, σ ₁²) and Y ₁, Y ₂, …Y ₁₀ be another random sample from normal N (µ ₂, σ ₂²), independently to each other. The test of hypothesis is

The sample size of X is n = 12 and Y is m = 10

The test is depend upon the population variance is kno

Let X denotes the test is positive and Y denotes the person has disease. Given that 5 % of cases, the test shows positive even when the subject does not have the disease that is

where denotes the person has no disease. Also given the test positive with probability 1

Then the conditional probability that you have the dis

Let X follows Poisson distribution with parameter m. The density function is

The r ^th factorial moment of Poisson distribution is

The
