Conduct a hypothesis test for each problem, using the traditional method (do not use the P-Value method). The president of a university claims the standard deviation of ages at his university is 2. A stats professor gathers a random sample of 20 students and finds the sample standard deviation to be 2.9. Use this data to test the president's claim at 0.1 level of significance.

(b) Assume the population standard deviation is σ = 0.6. Perform a hypothesis test at the α = 0.10 level to determine whether the mean GPA for business students is less than the mean GPA at the whole university. Use the P-value method with the table. State the null and alternate hypotheses. H0: H1: This hypothesis test is a (Choose one) test.

Test the hypothesis that σ1 ≠ σ2 at the α = 0.05 level of significance for the given sample data. Assume that the populations are normally distributed. Use the P-value approach. Population 1 Population 2 n 11 11 s 2.9 3.7 State the null and alternative hypotheses for this test. H0: σ1 = σ2 H1: σ1 ≠ σ2 Use technology to find the P-value for this test. The P-value is . (Round to three decimal places as needed.) Make a statement regarding the null hypothesis and draw a conclusion for this test. Since the P-value is the α = 0.05 level of significance, the null hypothesis. There sufficient evidence to conclude that the standard deviation of Population 1 is significantly different from the standard deviation of Population 2 at the α = 0.05 level of significance.

Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Unless specified by your instructor, use either the traditional method or P-value method for testing hypotheses. Identify the mull and alternative hypotheses, test statistic, $P$-value (or range of P-values), critical value(s), and state the final conclusion that addresses the original claim. Researchers collected a simple random sample of the times that 81 college students required to earn their bachelor's degrees. The sample has a mean of 4.8 years and a standard deviation of 2.2 years (based on data from the National Center for Education Statistics). Use a 0.05 significance level to test the claim that the mean time for all college students is greater than 4.5 years.
