cells in your output so the results are easier to read. Before reporting your results below consider the following: How many tails are you using for this test based on our statistical hypothesis? Report your results for that particular test! 4. Answer the following questions, feel free to round numbers with numerous decimal places. *Note, the following number format "aE-bb" is short for the number a x 10bb, which means you have a very small number! If your number is less than 0.001, feel free to write this as < 0.001. a. What is the number of observations (sample size, # of trees sampled) for the deciduous and evergreen categories? 70 and 101 b. What are the variances for your deciduous and evergreen categories? 3.471428571 and 41.04950495 c. What are your degrees of freedom (df)? 105 d. What WOULD your df be if you had equal variances? The formula is: (N₁ - 1) + (N₂ - 1). 169 e. What is the absolute value of your test stat? 6.388418679 f. What is your critical value for the type of test you want to do (think about how many tails you want to use for this test)? g. What is your p-value for the type of test you wanted to do (how many tails?) h. Can you reject the null hypothesis and why? i. What is this result telling you?

Question
Please answer 4f, 4g, 4h, 4I and the question above #4
In this tab, we will run a statistical test to help us determine whether the bagworm is really preferring evergreen trees and shrubs over deciduous trees and shrubs. In this problem we are treating bagworm number as a continuous variable. Our statistical null hypothesis for this test is: The mean number of bagworms on evergreen trees will be the same as the mean number of bagworms on deciduous trees. Our statistical alternate hypothesis for this test is: The mean number of bagworms on evergreen trees will be different than the mean number of bagworms on deciduous trees. 1. Because you will be comparing the means of two groups and you are not specifying which direction the difference will be in, which test should you use? Highlight the correct answer below using the same color font you have been using for your other answers. i. Unpaired student's t-test, one-tailed ii. Unpaired student's t-test, two-tailed iii. Paired student's t-test, one-tailed iv. Paired student's t-test, two-tailed v. One-way ANOVA, one-tailed vi. One-way ANOVA, two-tailed vii. Two-way ANOVA
