The mean of a normally distributed population is 15. A random sample of 15 measurements from the said population were selected producing x-17.25 and s 13.15. Test the null hypothesis against the alternative hypothesis u> 15 using a- 0.05. Steps Solution 1. Population parameter of interest 2. Formulate the null and alternative hypotheses. 3. Identify the appropriate test statistic. 4. Set the level of significance. Determine if the test is one or two tailed. Determine the critical value. 5. Decision rule for rejecting or not rejecting the null hypothesis
