3. A study was conducted to relate birthweight ( measured in hundreds of grams) and estriol level ( measured in mg/24hr) in 11 pregnant women. A simple linear regression model was fit to the sample data. Use the output from this page to answer the following questions.

The p-value for this test is - So, at a significance level of a = 0.05, we would (circle one): accept the null hypothesis / reject the null hypothesis / fail to reject the null hypothesis and conclude that give your conclusion in the context of the problem of interest and be as specific as possible about the direction and magnitude of any effect)
