On a standardized spatial skills task, normative data reveal that people typically get u = 15 correct solutions. A psychologist test n = 7 individuals who have brain injuries in the right cerebral hemisphere. For the following data, determine whether or not right- hemisphere damage results in significantly reduced performance on the spatial skills task. Test with alpha = .05 and a one-tailed %3D distribution. The data are as follows:

## Question 9

On a standardized spatial skills task, normative data reveal that people typically get μ = 15 correct solutions. A psychologist tests n = 7 individuals who have brain injuries in the right cerebral hemisphere. For the following data, determine whether or not right-hemisphere damage results in significantly reduced performance on the spatial skills task. Test with alpha = .05 and a one-tailed distribution.

The data are as follows:
12, 16, 9, 8, 10, 17, 10

What is the t value for this study?

- \( t_{\text{sample}} = 4.882 \)
- \( t_{\text{sample}} = 2.87 \)
- \( t_{\text{sample}} = - 2.49 \)
- \( t_{\text{sample}} = 0.424 \) (Correct Answer Highlighted)

This question assesses the understanding of calculating the t-value for a single sample t-test given the mean and sample data.
