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? Pine Trees Spruce Trees

Sample Size 70 80

Mean Trunk diameter, cm 36 34 Population variance 125 157

options:

The data does not support the conclusion that the average pine tree trunks are larger because the test value 0.53 is less than the critical value1.28.

The data does not support the conclusion that the average pine tree trunks are larger because the test value 1.03 is less 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 1.03 is less 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 23.05 is greater than the critical value 1.65.
