Consider the following hypotheses: H0: μ HA: H 130 130 A sample of 74 observations results in a sample mean of 125. The population standard deviation is known to be 31. Use Table 1 a. What is the critical value for the test with α 0.10 and with α-0.01? (Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.) α= 0.10 α = 0.01 b-1. Calculate the value of the test statistic. (Negative value should be indicated by a minus sign. Round your answer to 2 decimal places.) Test statistic b-2. Does the above sample evidence enable us to reject the null hypothesis at α = 0.10? O Yes since the value of the test statistic is less than the negative critical value. ONo since the value of the test statistic is not less than the negative critical value. Yes since the value of the test statistic is not less than the negative critical value. No since the value of the test statistic is less than the negative critical value. c. Does the above sample evidence enable us to reject the null hypothesis at α= 0.01? O No since the value of the test statistic is not less than the negative critical value. O Yes since the value of the test statistic is less than the negative critical value. O Yes since the value of the test statistic is not less than the negative critical value. No since the value of the test statistic is less than the negative critical value.
