Expert Solution

Step 1

The procedure of testing any hypothesis is given as follows:

First, define the hypothesis.

The null hypothesis is the statement about the population parameter, such a hypothesis is usually of no difference.
An alternative hypothesis is complementary to the null hypothesis.

Then, the level of significance should be decided.
Compute the test statistics.
Finally, compare the test statistics with the tabulated value at the given level of significance to decide whether to accept or reject the hypothesis.

There are various methods of testing the hypothesis like t-test, Z-test, F-test, and chi-square test.
