A field researcher is gathering data on the trunk diameters

A field researcher is gathering data on the trunk diameters of mature pine and spruce trees in a certain area. The following are the result of his random sampling. Can he conclude, at Alpha = 0.10, that the average trunk diameter of a pine tree is greather than tha average diameter of a apruce tree? The data does not support the conclusion that the average pine tree yranks are large because the test value 1.09 is less than than the critical value 1.28. The data supports the conclusion that tha average pine tree trunks are larger because the test value 2.56 is greater than than the critical value 1.28. The data supports the conclusion that tha average pine tree trunks are karger because the test 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 26.92 is greater than than tha critical value 1.65.
