![]() More specifically, the p-value is the smallest value of α that results in the rejection of H 0. Usually, the smaller the p-value, the stronger the sample evidence is for rejecting H 0. The p-value is a measure of the strength of the evidence in your data against H 0. In this case, that’s the probability of concluding that the population mean is not 25 mpg, when in fact it is. α is the probability of rejecting H 0 when H 0 is true. The most common way is to compare the p-value to the significance level, α (alpha). ![]() You need to know whether there is enough sample evidence to reject H 0. But the mean miles per gallon of all cars of this type (μ) might still be 25. The results show that the mean of the 35-car sample is 23.657.
