Answer:

Inference for Regression

Step-by-step explanation:

Let us try to understand the difference between each of them.

1) Two  sample t- test : the following assumptions must be used while applying the t- tests.

  1. The samples of n observations X₁,X₂,X₃,...........X n is selected  randomly.
  2. The population from which the small sample is drawn is normal.This is essential for X` and s , the two components of the statistics t, to be independent. it has , however been shown that slight departures from normality do not seriously effect the tests.
  3. <em>In case of two small samples both the samples are selected randomly , both the populations are normal and both the populations have equal variances.</em>

2) Chi - squared Test for independence:

The two attributes A and B are said to be independent if the actual frequency equals the expected one , that is, if  (AB) = (A)(B)/ N

Similarly α and β will be independent is (αβ) = ( α)( β)/ N and so on.

3) Inference for Regression

When both X and Y are observed at random i.e the sample values are from a bi variate population there are two regression equations , each obtained by choosing that variable as dependent whose average value is to be estimated and treating the other variable as independent .

4) A N O V A

The  various sources of variation , degrees of freedom , the sum of squares and the mean squares associated  with the sources are generally shown in a table called analysis of variance table or A N O V A table.

5) Matched pairs

It can be used when the experiment has only two events or possibilities and each variable can be grouped in either of the two conditions. Example people having C O V I D 19 and not having C O V I D 19.
