The table below contains means and standard deviations from two separate papers published by different researchers. Researcher A argued that elderly people who are caring for an Alzheimer's spouse at home are better off than those whose spouse is institutionalized, and Researcher B reached the opposite conclusion. Did the two populations differ in age, SES, social support, or health of non-Alzheimer participant? All indexes are scored such that higher scores mean more (i.e., higher SES, more social support, better health). 1) Conduct four independent t-tests to determine if the study populations differ. Interpret your results and report them in APA format. Note: for all four variables, you need to nd (\"1; df2; dfTotal; tcrit; SzPooled; SZDifference; SDifference; 1[obi 2) Can your results explain why the researchers obtained different answers? Explain.
