Step 1
State the null and alternative hypotheses: - Null hypothesis: The mean GPA is equal to or greater than 3.7 (H0: μ ≥ 3.7) - Alternative hypothesis: The mean GPA is less than 3.7 (Ha: μ < 3.7) Show more…

Test the claim that the mean GPA of night students is smaller than 3.2 at the 0.01 significance level. Based on a sample of 25 people, the sample mean GPA was 3.18 with a standard deviation of 0.02. Find the test statistic and p-value.

Test the claim that the mean GPA of night students is smaller than 2.3 at the 0.05 significance level. The null and alternative hypotheses would be: H0: p = 0.575 H1: p < 0.575 H0: p = 0.575 H1: p > 0.575 H0: μ = 2.3 H1: μ < 2.3 H0: μ = 2.3 H1: μ > 2.3 H0: p = 0.575 H1: p ≠ 0.575 H0: μ = 2.3 H1: μ ≠ 2.3 Based on a sample of 50 people, the sample mean GPA was 2.26 with a standard deviation of 0.03. The test statistic is -9.429 (to 3 decimals) The critical value is 2.405 (to 3 decimals)

Let X be a normal random variable with parameters μ = 8 and σ = 3.5. Find the following probabilities. p(x < 3) p(x > 11) p(3 < x < 11.5) 2. A sample of 40 junior high students had a mean GPA of 2.8 over all their courses taken in their first semester. This sample had a standard deviation of 0.25. Perform a hypothesis test at α = 0.05 to determine if the first semester GPA of all IWU freshmen is less than a B (3.0).
