What are the three ways to check a hypothesis test?

1. Test statistics-> mean or X-the hypothesis and divide it by st/sqrt of n 2. Find p-value-> use the formula t.dis.2t and plot in the value of the test statistics and n-1. If the p value is lower that the significant level we reject it 3. Confidence interval: x+/-z-value *s or st debv/ sqrt of n. Formula depends on sample size.
