3. The aquatic ecologist writes a small grant, reports his preliminary results, and receives funds to conduct a larger version of his study with 10 times as many fingerling trout (i.e., n = 60). Amazingly, he observes exactly the same growth response. In other words, in the control group, 10 trout grew 30mm, 10 grew 40mm, and 10 grew 50mm. In the high-salt group, 10 trout grew 10mm, 10 grew 20mm, and 10 grew 30mm. For each of the following, indicate whether and how the following attributes would change in your analysis, i.e., explain the direction of change(s), the quantitative nature of the change(s), and the underlying reason for any change.

a. Slope of regression line

b.Intercept of regression line

c.t-statistic for slope coefficient

d.P-value of test of null hypothesis
