3. Assume that you want to test the claim that the paired sample data come from a population. Use Critical Method to make decision. A farmer has decided to use a new additive to grow his crops. He divided his farm into 10 plots and kept records of the corn yield (in bushels) before and after using the additive. The results are shown below. Plot: Before 9 10 11 1 2 4 7 9. 6. 9. 10 After 10 9 8 7 10 10 10 12 You wish to test if the use of new additive increases the corn yield at the 5 percent level of significance. (Critical Method). ža = -0.9,sa = 0.56, where d is the difference between before and after (before - after).Show all your work and graph.

Several years ago, the state of California launched an aggressively advertisement campaign against smoking. We've interviewed students from 16 college campuses in California and recorded for each campus the percentage of students who claimed that they had encountered assay least one anti smoking advertisement on campus in the past month.  Here are those percentages.  53 39 30 49 48 42 41 38 26 36 40 42 52 51 45 50 Construct a box and whisker plot for the data.

Part II. The data below represents the weights (in kgs) of a sample of 20 giant turtles: 61 65 67 67 69 73 74 74 74 77 77 78 80 84 88 89 92 93 95 96 1. Construct a Stem-and-Leaf display of this data based on the stems 6, 7, 8, 9. 2. Find the percentage of weights greater than or equal to 73 kgs. 3. Find the percentage of weights less than 80 kgs.

1. The maximum number of sit-ups completed by the participants in an exercise class after 1 month of the program is given below. Construct a two-stem stem and leaf plot.   24 31 54 62 36 28 55 18 27 80 37 58 32 37 41 55 39 56 42 29 35 35     2. Find the mean, median, 20% trimmed mean, first quartile, and third quartile for the data in question 3. Show your work for credit.         3. A statistics class has 20 female students and 10 male students. Average exams score for the females is 78.5 and the average exam score for the males is 72.1. What is the average exam score of the entire class?

Draw the box-and-whisker plot and give the five-number summary for each data set. Number of games won by the Detroit Lions in their last 10 seasons:                                                      minumim:________            (9,7,11,7,4,10,6,2,0,7)                                                                                                                 Lower Quartile:________                                                                                                                                                                  Median:______________                                                                                                                                                        Upper Quartile:_____________                                                                                                                                                         Maximum_______________

It is generally believed that there is a relationship between a college’s acceptance rate and its graduation rate. I wanted to know how strong this relationship is within the top universities in the country so I collected the graduation rate and acceptance rate data of a randomly selected sample of universities from all the top U.S. universities (with an acceptance rate at or below 30%). The data set is in Tab Q2 of the Excel data file. a.) Create a scatter plot between the two variables using Excel. Paste the plot here and format it into an APA-styled “figure” (see Assignment Guides for APA format).Be sure to submit the Excel file that you used to create the scatter plot.     b) Calculate the mean and standard deviation for the two variables separately.   c) Calculate the Z scores for all the scores of the two variables, separately.Tips: It may help to prevent error and to increase clarity if the process and/or the answers (z scores) are listed in a table format.     d) Calculate…
