WebA statistics class at a large high school suspects that students at their school are getting less than eight hours of sleep on average. To test their theory, they randomly sample 42 … WebMar 26, 2024 · The relevant test is H0: μ = 7.4vsHa: μ ≠ 7.4 @ α = 0.01 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. Inserting the data into the formula for the test statistic gives Z = ˉx − μ0 s / √n = 7.7 − 7.4 0.5 / √30 = 3.29
