(a) Use our researcher's bamboo data to test the appropriateness of the linearity assumption for the simple linear regression model. (b) In reference to the test in part (a), why did we say in the text, “Of course, this really should be a test of significance”? (c) Give the decision rule for the situation described in the text just above where you are “. . . monitoring the height of bamboo shoots … with the intention of altering the watering schedule if it ever appears that the daily rate of growth falls below 8 em.” Assume- a = 5%. (d) Would the research worker's second set of data given in the text cause you to alter the watering schedule? (e) Compare the tests in parts (a) and (c). Why is the first a two-tailed test and the second not?
