1. Research Scenario: A college professor administers a vocational interest inventory to a sample of business majors at the university where he teaches. He believes that they will have higher scores on the \"Enterprising\" scale than students in the general population, who normally score a 42. The table below shows the scores of the business majors on the \"Enterprising\" scale of the vocational interest inventory. Using the table, enter the data into a new SPSS file and conduct a one-sample t test to evaluate whether these scores are significantly higher than those of the general population of college students.The steps of the test will be the same as the ones you have been practicing in Part One of the assignmentthe only difference is that you are now responsible for creating the data file as well. Remember to name and define your variables under the \"Variable View,\" then return to the \"Data View\" to enter and analyze the data. Enterprising Scale Scores 47 49 52 33 29 48 30 48 36 57 51 47 a. Paste SPSS output. (2 pts) b. Write an APA-style Results section based on your analysis. All homework \"Results sections\" should follow the example given in the SPSS tutorials and the Course Content document \"Writing Results of Statistical Tests in APA Format.\" Remember to include a decision about the null hypothesis. (3 pts) c. Create a histogram that demonstrates the distribution of scores. Be sure to correctly label the X and Y axes and give your graph a title. (2 pts) 2. Research Scenario: A researcher is interested in whether pairs of identical twins have similar Math Subject SAT scores in late high school. She collects scores from 11 twin pairs, which are shown in the table below. Conduct a paired-samples t test to determine whether there is a difference in the SAT scores of identical twins. The steps will be the same as the ones you have been practicing in Part One of the assignment the only difference is that you are now responsible for creating the data file as well. Remember to name and define your variables under the \"Variable View,\" then return to the \"Data View\" to enter the data. Twin 1 Twin 2 630 577 698 409 499 701 634 656 723 684 621 503 723 450 474 659 617 683 702 690 a. Paste SPSS output (2 pts) b. Create a boxplot comparing the twins' scores. Be sure to correctly label the X and Y axes. (2 pts) c. Write an APA-style Results section based on your analysis.
