“The Null Hypothesis (abbreviated H0) states that population parameters are equal (or equal to s specific value). There is NO difference between the parameters being studied.
The Alternative Hypothesis (abbreviated H1) states that the population parameters are unequal (or NOT equal to a specific value). In other words, a difference exists between the parameters being studied.
The Null hypothesis and the Alternative hypothesis are mutually exclusive. That is to say, only one can be true.”
