WebMar 5, 2024 · We notice that, P-value < Significance Level. This means that, in this problem statement and the hypothesis, finding a sample mean value of 535.5 has a probability of 0.002 or 0.2%, which is extremely less than the significance level (0.05 or 5%) and is considered too far away from the population mean (500). WebNote that you can compute a p -value (and a CI) with just a mean, SD, and N from each group. Often, a paper will report a p-value, and you’ll want to compute a CI; it can be done (see Mutolsky , Intuitive Biostatistics). One-Tailed and Two -Tailed p -values The p-values we have been computing so far are two-tailed p-values.
