QUESTION 3 Given a simple random sample of size n = 22 from a Normal population with mean and standard deviation, we test the hypotheses HO: 30 H1: <30. If is known, and the observed value of the test statistic is -1.87, determine the p-value of the test (give answers correct to 3 decimal places). QUESTION 4 Given a simple random sample of size n = 22 from a Normal population with mean and standard deviation , we test the hypotheses HO:u=30 H1: <30. If σ is unknown, and the observed value of the test statistic is -1.87, determine the p-value of the test (give answers correct to 3 decimal places). QUESTION 5 Given a simple random sample of size n = 18 from a Normal population with mean and standard deviation σ, we test the hypotheses HO:μ = 2.5 H1:p>2.5, at the 5% significance level. If σ is known, and the observed value of the test statistic is 1.77, determine the result of the test. O More information is required to determine the result of the test. O The test rejects Ho in favour of H₁. O The test does not reject Ho in favour of H1₁. 1 points 1 points 1 points Save Answer Save Answer Save Answer
