Suppose you're interested in studying state-level differences in mortality in the United States. A random sample of the mortality records of 1,000 California residents yields a mean age of death of 79.0 years with a standard deviation of two years. A random sample of the mortality records of 1,000 Texas residents, however, yields a mean age of death of 77.0 years with a standard deviation of four years. Test the hypothesis that there is a DIFFERENCE (the fact that the word "difference" is capitalized, bolded, and highlighted should give you a clue as to how to set this problem up) in the mean ages of death of California and Texas residents. Assuming an alpha level of 0.05, what is your conclusion regarding the mean age of death of California and Texas residents, respectively? Group of answer choices Because the absolute value of the obtained statistic is greater than the critical statistic, we reject the null hypothesis. Because the absolute value of the obtained statistic is greater than the critical statistic, we can't reject the null hypothesis. Bummer. Because the absolute value of the obtained statistic is less than the critical statistic, we reject the null hypothesis. Because the absolute value of the obtained statistic is less than the critical statistic, we can't reject the null hypothesis
