Question 1 An field researcher is gathering data on the trunk diameters of mature pine and spruce trees in a certain area. The following are the results of his random sampling. Can he conclude, ata=0.10, that the average trunk diameter of a pine tree is greater than the average diameter ofa spruce tree? Sample size Mean trunk diameter, cm Population variance Pine trees 40 36 115 10 pts Spruce trees 60 30 157 The data supports the conclusion that the average pine tree trunks are larger because the tost value 2.56 is, greater than than the critical value 1.65. The data does not support the conclusion that the average pine tree trunks are larger because the test value 27.23 is greater than than the critical value 1.65. The data supports the conclusion that the average pine tree trunks are larger because the test value 2.56 is greater than than the critical value 1.28. The data does not support the conclusion that the average pine tree trunks are larger because the test value 1.09 is less than than the critical value 1.28.
