A hypothesis test examines two opposing hypotheses about a population: the null hypothesis and the alternative hypothesis. How you set up these hypotheses depends on what you are trying to show.
Null hypothesis (H0)
The null hypothesis states that a population parameter is equal to a value. The null hypothesis is often an initial claim that researchers specify using previous research or knowledge.
Alternative Hypothesis (H1)
The alternative hypothesis states that the population parameter is different than the value of the population parameter in the null hypothesis. The alternative hypothesis is what you might believe to be true or hope to prove true.
Some common hypotheses
Hypothesis to determine whether a population mean, , is equal to some target value 0 include the following:Ho: = 0 H1: < 0 (a lower-tailed test) or H1: > 0 (a upper-tailed test) or H1: 0 (a two-tailed test)
Hypothesis to determine whether one population mean, 1 is equal to different population mean 2include the following:H0: 1 = 2 H1: 1< 2 or H1: 1> 2 or H1: 1 2
