21. (8 points) A 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, at a = 0.10, that the average trunk diameter of a pine tree is greater than the average diameter of a spruce tree? Use P-value method. Pine trees Spruce trees X1 = 36 X2 = 32 01 = 10.2470 02 = 11.2694 n1 = 60 n2 = 70 Parameter's name and symbol: Claim: State the given data: Circle the appropriate test: 2 - SampleZTest Statistics 2-PropZTest 7 Statistics 2 - SampleFTest\\ Data 1 State the null and alternative hypotheses, indicate the Tail-test, and identify the claim.
