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 the .10 level of significance, that the average trunk diameter of a pine tree is greater than the average diameter of a spruce tree?
Stands of aspen trees often are a series of genetically identical individuals, with each succeeding tree growing from the severed shoot of another tree. Using what you've learned of genetics would you expect one aspen tree in a stand to differ greatly from another in its phenotype? Would you expect each to look exactly like the

If you were to draw a scatter plot of the number of women in the work force versus number of Christmas trees sold in the United States annually between 1930 and the present, you would find a strong positive correlation.
Why do you think this would be true?

Researchers conducted experiments with trees. Listed below are wights (kg) of trees given no fertilizer and trees treated with fertilizer and irrigation, Find the range, variance and standard deviation for each of the two samples, then compare the two sets of results. Does there appear to be a difference between the two stand

Netty produces Christmas tree ornaments for resale at local craft fairs and Christmas bazaars. She is currently working a total of 15 hours per day to produce 300 ornaments.
a) What is Netty's productivity?
b) Netty thinks that by redesigning the ornaments and switching from contact cement to a hot-glue gun, she can increase h
My problem is setting up a quadratic function for this problem:
Research has shown that if 100 apple trees are planted, then the annual revenue is 90$ dollars per tree. If more trees are planted, they have less room to grow and generate fewer apples per tree. As a result, the annual revenue per tree is reduced by 0.70$ per ea
Walters, a grower of Christmas trees, contracted to supply Traynor with "top-quality trees." When the shipment arrived and was inspected, Traynor discovered that some of the trees were not top quality. Within 24 hours, Traynor notified Walters that he was rejecting the trees that were not top quality. Walters did not have a plac
Suppose you want to cover the backyard with decorative rock and plant some trees as the first phase of the project. You need 30 tons of rock to cover the area. If each ton cost $60 and each tree is $84, what is the maximum number of trees you can buy with a budget for rock and trees of $2500? Write an inequality that illustrat
