For paired t, the hypotheses are as follows.
Null hypothesis
H0: μd = μ0 The population mean of the differences (μd) equals the hypothesized mean of the differences (μ0).
Alternative hypothesis
Select one of the following alternative hypotheses.
H1: μd ≠ μ0 The population mean of the differences (μd) does not equal the hypothesized mean of the differences (μ0).
H1: μd > μ0 The population mean of the differences (μd) is greater than the hypothesized mean of the differences (μ0).
H1: μd < μ0 The population mean of the differences (μd) is less than the hypothesized mean of the differences (μ0).
