WebThe P-value for conducting the left-tailed test H 0: μ = 3 versus H A: μ < 3 is the probability that we would observe a test statistic less than t* = -2.5 if the population mean μ really were 3. The P-value is therefore the area under a t n - 1 = t 14 curve and to the left of the test statistic t* = -2.5.
