Complete Parts A and B.Part ASome questions in Part A require that you access data from Statistics for People Who (Think They) Hate Statistics. This data is available on the student website under the Student Text Resources link.Using the data in the file named Ch. 11 Data Set 3, test the null hypothesis that urban and rural residents both have the same attitude toward gun control. Use IBM® SPSS® software to complete the analysis for this problem.In the following examples, indicate whether you would perform a t test of independent means or dependent means.Two groups were exposed to different treatment levels for ankle sprains. Which treatment was most effective?A researcher in nursing wanted to know if the recovery of patients was quicker when some received additional in-home care whereas when others received the standard amount.A group of adolescent boys was offered interpersonal skills counseling and then tested in September and May to see if there was any impact on family harmony.One group of adult men was given instructions in reducing their high blood pressure whereas another was not given any instructions.One group of men was provided access to an exercise program and tested two times over a 6-month period for heart health.For Ch. 12 Data Set 3, compute the t value and write a conclusion on whether there is a difference in satisfaction level in a group of families use of service centers following a social service intervention on a scale from 1 to 15. Do this exercise using IBM® SPSS® software, and report the exact probability of the outcome.Using the data in Ch. 13 Data Set 2 and the IBM® SPSS® software, compute the F ratio for a comparison between the three levels representing the average amount of time that swimmers practice weekly ( 25 hours) with the outcome variable being their time for the 100-yard freestyle. Does practice time make a difference? Use the Options feature to obtain the means for the groups.From Salkind (2011). Copyright © 2012 SAGE. All Rights Reserved.

This data is available on the student website under the Student Text Resources link.The data for Exercise 14 is in thedata file named Lesson 22 Exercise File 1.John is interested in determining if a new teaching method, the involvement technique, is effective in teaching algebra to first graders. John randomly samples six first graders from all first graders within the Lawrence City School System and individually teaches them algebra with the new method. Next, the pupils complete an eight-item algebra test. Each item describes a problem and presents four possible answers to the problem. The scores on each item are 1 or 0, where 1 indicates a correct response and 0 indicates a wrong response. The IBM® SPSS® data file contains six cases, each with eight item scores for the algebra test.Conduct a one-sample t test on the total scores. On the output, identify the following:Mean algebra scoreT test valueP valueThe data for Exercise 15 is in thedata file named Lesson 25 Exercise File 1.Marvin is interested in whether blonds, brunets, and redheads differ with respect to their extrovertedness. He randomly samples 18 men from his local college campus: six blonds, six brunets, and six redheads. He then administers a measure of social extroversion to each individual.Conduct a one-way ANOVA to investigate the relationship between hair color and social extroversion. Conduct appropriate post hoc tests. On the output, identify the following:F ratio for the group effectSums of squares for the hair color effectMean for redheadsP value for the hair color effectFrom Green & Salkind (2011).
