We apply the lm function to a formula that describes the variable eruptions by the variable waiting, and save the linear regression model in a new variable eruption.lm . > eruption.lm = lm (eruptions ~ waiting, data=faithful) Then we print out the F-statistics of the significance test with the summary function. > summary (eruption.lm)
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.
