A researcher would like to know whether there is a consistent, predictable relationship between verbal skills and math skills for high school students using a sample of 200 students. Each student is given a standard English test and a standardized English test and a standardized math test. Based on then test results, students are classified as either high or low for verbal skills and for math skills, respectively. The results are summarized in the following frequency distribution table: Verbal Skills High Low Maths Skills High 59 41 Low 31 69 a. Based on these results, can the researcher conclude that there is a significant relationship between verbal skills and math skills? Test at the .05 level of significance. (Use manual computations and show all calculations) b. What calculations can be reached based on this result?
