In a hypothesis test the p-value is
WebThe p-value tells us how likely it is to get a sample mean of 25 when the sample mean should be close to 20. If, as at 5:31 , the p-value = 0.03, then the probability of randomly … WebThis chart has two shaded regions because we performed a two-tailed test. Each region has a probability of 0.01559. When you sum them, you obtain the p-value of 0.03118. In other words, the likelihood of a t-value falling in either shaded region when the null hypothesis is true is 0.03118. I showed you how to find the p value for a t-test.
