We have data on date of and age at đeath for Cemetery. For a matched pair study (investigating whether people buried later lived longer lives), we randomly select 40 burials in the period 1900-1910 and match each with a burial twenty years later (in the period 1920-1930). Ages at death for the later burials are subtracted from ages at death for the earlier burials. The mean difference is 12.52 years with standard deviation 39.16 Answer the following questions, providing explanation: a) Do we need degrees of freedom for this study, and (if we do) wh should we use? b) What will you use for the alternative hypothesis? C) Is this a left-tailed, right-tailed, or two-tailed test? d) Find the value of the test statistic.

We have data on date of and age at death for various burials in Geer Cemetery. For a matched pair study (investigating whether people buried later lived longer lives), we randomly select 40 burials in the period 1900-1910 and match each with a burial twenty years later (in the period 1920-1930). Ages at death for the later burials are subtracted from ages at death for the earlier burials. The mean difference is 12.52 years with standard deviation 39.16 Answer the following questions, providing explanation: (a) Do we need degrees of freedom for this study, and (if we do) what should we use? (b) What will you use for the alternative hypothesis? (c) Is this a left-tailed, right-tailed, or two-tailed test? (d) Find the value of the test statistic.
