How to figure out the null hypothesis

WebTest statistics represent effect sizes in hypothesis tests because they denote the difference between your sample effect and no effect —the null hypothesis. Consequently, you use the test statistic to calculate the p-value for your hypothesis test. The above p-value definition is a bit tortuous. WebAnd if you figured out this area, and you could actually figure it out by looking at a Z-table, you could figure out the P-value of this result. But anyway, the whole exercise here is just to figure out if can reject the null hypothesis with a significance level 5%. We can.
