The following values of a response Y were obtained for three settings of a categorical predictor A.

A = 1 0.090 0.800 33.070 −1.890

A = 2 5.120 1.580 1.760 1.740

A = 3 5.080 −3.510 4.420 1.190

Suppose we assume the normal regression model for these data with one categorical predictor.

a) If you have been able to fix any problems encountered with the model, carry out a one-way ANOVA to test for any differences among the conditional means of Y given A.

b) If warranted, construct 0.95-confidence intervals for the differences between the means and summarize your findings

Question 3 Suppose that the estimated simple linear regression of a response Y on a predictor X based on n = 6 observations produces the following residuals: resid <- c(-0.09, 0.18, -0.27, 0.16, -0.06, 0.09) Note: For this question, all of the computations should be performed “by-hand”. (a) (1 point) What is the estimate of σ 2? (b) (2 points) Further, you know that the estimated regression parameters are βˆ 0 = −0.54 and βˆ 1 = 0.08. Additionally, the...

(7) The following values were obtained for the nitrate concentration (mg/L) in a sample of river water: 0.403, 0.410, 0.401, and 0.380. The last measurement is suspect. Based on this data set only, should it be rejected? Justify your answer. (8) Three further measurements were added to those given in question (7) so that the complete results became: 0.403, 0.410, 0.401, 0.380, 0.400, 0.413, and 0.411. Should “0.380” still be retained/rejected? Justify your answer. (9) Based on questions (7) and...
