1. This problem uses the wblake data set in the alr4 package. This data set includes samples of small mouth bass collected in West Bearskin Lake, Minnesota, in 1991. Interest is in predicting length with age. Finish this problem without using Im(). (a) Compute the regression of length on age, and report the estimates, their standard errors, the value of the coefficient of determination, and the estimate of variance. Write a sentence or two that summarizes the results of these computations. (b) Obtain a 99% confidence interval for A from the data. Interpret this interval in the context of the data (c) Obtain a prediction and a 99% prediction interval for a small mouth bass at age 1 . nterpret this interval in the context of the data. 1.
