Expert Solution

Step 1

Hypothesis testing is conducted for the parameters of the population like population mean, population standard deviation and so on. It is to check whether the sample values conform to the prestated parameter values of the original distribution or not. The hypothesis for the single population mean is conducted using the z or t test. The selection of the test depends upon the value of the standard deviation.
