What is the best way to describe a polymer?

What term is used for a reaction rate that is not dependent upon the concentration of reactants?

The half-life of a medication is defined as what period of time?

What does the field of kinetics study in chemical reactions?

To what does the term “toxic compound” refer?

Problem #2 on your calculation sheet What does the alternative hypothesis predict?

Problem #3 on your calculation sheet. The Marine Life Institute has developed a media campaign designed to decrease the amount of trash pollution in the local harbors. Before the campaign began, researchers measured the amount of pollution (in pounds) pulled from each of the local harbors. After the campaign was over, they returned to the same harbors and measured the amount of pollution (in pounds) left in the harbors. The third data set on your calculation sheet (problem #3) shows how much pollution were present both before and after the media campaign. Column “Pre” shows the amount of pollution before the campaign and Column “Post” shows the amount of pollution after the campaign. We would like to know if the campaign made a difference in the amount of pollution the people caused in the harbors. What is the independent (or quasi-independent) variable in this study?

Problem #3 in your calculation sheet. Report the outcome of the hypothesis test and how you decided whether or not to reject the null hypothesis.

Problem #2 on your calculation sheet. How would you explain the results of this hypothesis test to a non-statistician? Explain any conclusions about the differences observed, or the lack thereof. If there was a statistically significant difference, be specific about the direction of the difference (i.e. which group had more or less of the outcome of interest). You do not need to include your APA statistical values, just explain the results in sentence format. 

Problem #1 on your calculation sheet The Academic Scholars committee is currently having a fundraising campaign. Their goal is to obtain an average of $20.00 from each contributor. The first data set you worked with (Problem #1) consists of contributions given to the alumni foundation so far. The foundation wants to determine whether the contributions they have received so far are significantly different from their goal of $20.00. What value(s) does the null hypothesis predict for the mean?
