You may need to use the appropriate appendix table or technology to answer this question. Consider the following hypothesis test. Ho: μ ≥ 20 H₂: H <20 A sample of 50 provided a sample mean of 19.3. The population standard deviation is 2. (a) Find the value of the test statistic, (Round your answer to two decimal places.) -2.48 (b) Find the p-value. (Round your answer to four decimal places.) p-value = 0.0067 (c) Using a = 0.05, state your conclusion. Reject H. There is sufficient evidence to conclude that μ < 20. Reject Ho. There is insufficient evidence to conclude that u < 20. Do not reject Ho. There is sufficient evidence to conclude that μ< 20. Do not reject H₁. There is insufficient evidence to conclude that μ< 20.
