HOMEWORK ASSIGNMENT--BIO 112 STATISTICAL ANALYSIS

Your objective in this assignment is to analyze the data in the table below. Carry out all appropriate statistical tests and describe their outcomes and meanings. The work you will turn in will be in two parts. The first part will be a series of sentences describing the outcomes of statistical tests. You can think of these as sentences that could be in the "Results" section of a lab report. This part of the assignment, as well as the names of the students in your group, must be written on a typewriter or with a word processor in order to be graded. Number the sentences and include the T value at the end of the sentence. The second part of the paper will show your computations from doing each statistical test. These will be numbered to link them to the corresponding sentence in the first part. It is not necessary to type out this part of the assignment.
