Question on Images:

Using the 7 steps of hypothesis testing determine if individuals with brain injuries in the right hemisphere show lower scores on the test of spatial skills using α = .05

1. State your hypothesis in words

2. Statistical hypotheses

3. α

4. Decision rule (be sure to include critical value)

5. Calculate your statistic

6. Make your decision

7. State your results in a sentence, report in APA style. Be sure to include descriptive statistics and calculate one measure of effect size (you choose).

8. For your result above, what type of error is possible? What could the researcher do to make this type of error less likely?

Extracted text: On a standardized test of spatial skills, normative data reveal that people typically score u = 15. A psychologist tests n = 7 people with brain injuries in the right hemisphere to determine if their injuries are associated with lower scores on the test of spatial skills. The scores on the spatial skills test for the 7 individuals appear below. Using the 7 steps of hypothesis testing determine if individuals with brain injuries in the right hemisphere show lower scores on the test of spatial skills using a = .05 Spatial Skills Scores 12 16 9 8 10 17 10 EX = 82 X2 = 1034 S =3.50 m = 11.71
