WebSep 19, 2024 · The value we call p-value; In its simplest definition, the null hypothesis is a measure of how mathematically possible the result we get. The smaller our result, the stronger the evidence against the null hypothesis. ... If the result obtained is less than 0.05 (5%), the null hypothesis is rejected, that is, the result found is interpreted as ... 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.
