Question

In order to conduct a hypothesis test of the population mean, a random sample of 26 observations is drawn from a normally distributed population. The resulting mean and the standard deviation are calculated as 6.2 and 2.2, respectively. Use Table 2. Use the critical value approach to conduct the following tests at a =0.10. bolnts Ho:us 5.8 against HA > 5.8 2-1. Calculate the value of the test statistic. (Round your intermediate calculations to 4 decimal places and final answer to 2 decimal places.) Book Print Test statistic References a-2. Calculate the critical value. (Round your answer to 3 decimal places.) Critical value a-3. What is the conclusion? Do not reject Ho since the value of the test statistics is greater than the critical value. O Reject Ho since the value of the test statistics is smaller than the critical value. Reject Ho since the value of the test statistics is greater than the critical value. Do not reiert Ha since the value of the test statistire is smaller than the
