WebAboutTranscript. We compare a P-value to a significance level to make a conclusion in a significance test. Given the null hypothesis is true, a p-value is the probability of getting a result as or more extreme than the sample result by random chance alone. If a p-value is lower than our significance level, we reject the null hypothesis. WebRight-Tailed Test: t.test(x, y, mu= , alternative="greater") Left-Tailed Test: t.test(x, y, mu= ,alternative="less") Example 1: Test the claim that the mean cholesterol level for all men who use the drug is less than the mean for those who do not use the drug. Assume both populations are normally distributed and use a 0.05
