2. Find the predicted values and residuals for the first 3 observations in this data set. Number of plant species is the dependent variable. The slope of the regression is 1.55 and the y intercept is 156.7. Observation Annual Number of Predicted Residual precipitation (cm) plant species value per hectare 87.3 315 43.1 14.9 103 157.3 74.0 286 1 2 3 4 5 365 297

3. A study was conducted to determine if there was a difference between the mean nitrate concentration in three streams: Allen Creek, Bear Creek, and Bradley Creek. A sample of 6 observations was collected for each stream. The within group variance was 2.9 (mg/L) and the between group variance was 15.9 (mg/L). Use the traditional method to conduct an ANOVA test to determine if there is at least one difference between the means, with a significance level of 0.05. Remember, ANOVA is always a one- tailed test. D.f. denominator: a. Null and alternative hypotheses: b. Degrees of freedom of numerator: c. Critical value: d. Test value: e. Decision regarding Ho: f.
