The five-step processes for hypothesis testing are the following. Step1. Specify the null hypothesis H0 and alternative hypothesis H1. The null hypothesis is the hypothesis that the researcher formulates and proceeds to test. If the null hypothesis is rejected after the test‚ the hypothesis to be accepted is called the alternative hypothesis. For example if the researcher wants to compare the average value generated by two different procedures the null hypothesis to be tested is [pic] and

For example‚ we might need to decide whether the mean weight‚ μ‚ of all bags of pretzels packaged by a particular company differs from the advertised weight of 454 grams (g)‚ or we might want to determine whether the mean age‚ μ‚ of all cars in use has increased from the year 2000 mean of 9.0 years.
