You wish to test the following claim (Ha) at a significance level of a 0.005. Ho: μ-68.2 Ha: μ > 68.2 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n 30 with a mean of M 78.9 and a standard deviation of SD -14.7 What is the critical value for this test? (Report answer accurate to three decimal places.) critical value- What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = The test statistic is... Oin the critical region Onot in the critical regiorn
This test statistic leads to a decision to... Oreject the null Oaccept the null Ofail to reject the null As such, the final conclusion is that... There is sufficient evidence to warrant rejection of the claim that the population mean is greater than 68.2. There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 68.2 OThe sample data support the claim that the population mean is greater than 68.2. OThere is not sufficient sample evidence to support the claim that the population mean is greater than 68.2.
