Question

Hello,

I was hoping if you could please guide me becuase I am confuse.

A researcher would like to know whether there is a consistent, predictable relationship between verbal skills and math skills for high school students. A sample of 200 students is obtained, and each student is given a standardized English test and a standardized math test. Based on the test results, students are classified as high or low for verbal skills and for math skills. The results are summarized in the following frequency distribution:

	Verbal	Skills
Math Skills	High	Low
High	59	41
Low	31	69

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.
Compute the phi-coefficient to measure the strength of the relationship and report and discuss your findings.

Thank you.
