S.3.2 Hypothesis Testing (P-Value Approach) STAT ONLINE
WebConclusion: We do a two-tail test (inequality). lf t Stat < -t Critical two-tail or t Stat > t Critical two-tail, we reject the null hypothesis. This is not the case, -2.365 < 1.473 < 2.365. Therefore, we do not reject the null hypothesis. The observed difference between the sample means (33 ... WebLeft Tailed. In our example concerning the mean grade point average, suppose that our random sample of n = 15 students majoring in mathematics yields a test statistic t* instead equaling -2.5.The 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 … map ashwell

The relevant test is H0: μ = 202.5vsHa: μ < 202.5 @ α = 0.05. Step 2. The sample is large and the population standard deviation is unknown. Thus the test statistic is Z = ˉx − μ0 s / √n and has the standard normal distribution. Step 3. Web15 sep. 2024 · Perform the appropriate statistical test: Perform a t-test to see if the male teenagers are shorter than the female teenagers by finding the estimated differences in average heights between each group and the p-value. Your test shows that the height average is 175.2 for males and 167.6 for females. Therefore, the difference is 7.6 to infinity. map asia thailand
