Step 1: Step 2: The alternative hypothesis is which indicates a one tail test. The degrees of freedom (df) = n-2=12-2=10. The t value at the significance level of .05 and df of 8 and from appendix F is 1.812. The decision rule is to reject the null hypothesis because the test statistic is greater then 1.812. Step 3: According to Appendix F‚ we can assume that P 1.744)‚ there is insufficient evidence to reject the null hypothesis. P-value Approach: Since the P-value is less

A most recent inquiry into climatic change during the ice age and it ’s possibility of reoccurring is the Snowball Earth Hypothesis advanced by Paul Hoffman of Harvard University. Snowball Earth Suggest that before the Ice age‚ continents ice free at the poles enhanced the reabsorption of carbon dioxide through erosion of silicate minerals‚ reducing the greenhouse effect making the earth colder until it reached a runaway point. This effect is Hoffman calls albedo‚ when the atmosphere becomes so cold

conclusion‚ the purpose of the lab Bird Adaptations was to act as a bird using different tools as a beak‚ and try to collect as many items as you can at each station in 15 seconds. Overall‚ the data collected throughout this lab supported each of my hypothesis. The data shows that certain “beaks” worked better than the other at collecting food. For example‚ the data shows that for the Seeds Station the tweezers worked best with an average of 9.3 pieces of food‚ the straw worked best for the Nectar Station
