Question

Dr. Penner thinks that she can predict a person’s success at a spatial task from their Mental Ability Score (MAS). She asks 300 high-school students to complete the MAS (scores range from 10-50) and a series of spatial tasks (scores range from 0-15). She expects that with increased MAS high school students will be more successful at the spatial task.

What are the null and alternative hypotheses (use the appropriate symbols not words)?

What are the test’s assumptions?

If the research obtains a test statistic of ____ , would the researcher retain or reject H0?

Should the researcher do any follow up tests or make any graphs/charts?

Interpret the findings in APA style.

Explanation / Answer

Independent= Mental Ability Score (MAS)

Dependent=success at a spatial task

Ho: correlation =0

H1: correlation !=0

CORRELATION test should be used.

Test is appropriate as Dr. Penner thinks that she can predict a person’s success at a spatial task from their Mental Ability Score (MAS).So,we need to test correlation.

Assumption is that there is linear relationship between success at a spatial task from their Mental Ability Score (MAS).

df=300-2 =298

n is sample size

For rest of the part data is missing.
