Hypothesis Testing
Example 2: Weight Loss for Diet vs Exercise Step 3. Determine the p-value. Recall the alternative hypothesis was two-sided. p-value = 2 × [proportion of bell-shaped curve above 2.17] Table 8.1 => proportion is about 2 × 0.015 = 0.03. Step 4. Make a decision. The p-value of 0.03 is less than or equal to 0.05, so …

www2.stat.duke.eduIt seems clear that both age and gender have an e ect on someone’s survival, how do we come up with a model that will let us explore this relationship? Even if we set Died to 0 and Survived to 1, this isn’t something we can transform our way out of - we need something more. One way to think about the problem - we can treat Survived and Died as
