Chapter - 3 Classical Decision theory Test of Hypothesis Nonparametric Method
A multinomial trial with parameters p1 , p2 , , pk is a trial that can result in exactly one of the k possible outcomes. The probability that outcome i will occur on a given tri
Approximate Tests for Proportion
The tests for proportion p are derived using the normal distribution approximation to the binomial distribution. Theorem: If S is the number of successes in n independent Bernoulli trials of an experiment with a constant p
Preliminaries
Inferential Statistics is concerned with estimating the true value of population parameters using sample statistics. The 2 types Of Estimates are:Point Estimate Interval Estimate
Point Estimate:- Single sample statistic that is used to est

TEST OF HYPOTHESIS
TEST OF HYPOTHESIS
There are many problems in which, rather then estimating the value of a parameter, we need to decide whether to accept or reject statement about the parameter. This statement is called hypothesis and the decision maki

Numerical Analysis
Introduction:
Numerical Analysis is very important for mathematicians, Engineers and the related peoples because it provides the desired accurate solution

Is there any significant difference in means ? or Are the obtained means due to chance only ?

Analysis of Variance
By R. K. Pandey Mathematics Group, BITS-Pilani, Goa Campus.
We are interested to comparing the mean of a populations. Our interest is in testing the null hypothesis that the population means are equal.
