A researcher gathers data on a population of 300 people with type 2 diabetes across 5 states. She seeks to examine the effects of age (12-81), weight (normal, overweight), and average daily activity (hours per day) on the participants' ratings of daily average diabetes related discomfort (0-100). The researchers' first hypothesis suggests that participants in different weight classifications will have differences in their ratings of daily average diabetes related discomfort. What is the most specific inferential statistic the researcher should use to gather evidence for this hypothesis? a. Power Analysis b. Chi Square c. t-test d. one-tailed t-test e. two-tailed t-test f. ANOVA g. Cohen's d h. Pearson Correlation i. Multiple Regression j. Structural Equation Modeling
