question 50

Multiple Choice

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, at = 0.10, that the average trunk diameter of a pine tree is greater than the average diameter of a spruce tree?

• A) The data does not support the conclusion that the average pine tree trunks are larger because the test value 0.53 is less than than the critical value1.28.
• B) The data does not support the conclusion that the average pine tree trunks are larger because the test value 1.03 is less than than the critical value 1.28.
• C) The data does not support the conclusion that the average pine tree trunks are larger because the test value 1.03 is less than than the critical value 1.65.
