Final answer:

Wendy has made a Type I error in statistical hypothesis testing.

Step-by-step explanation:

Wendy has made a Type I error in statistical hypothesis testing. A Type I error occurs when the null hypothesis is incorrectly rejected, leading to a false positive conclusion. In this case, Wendy concluded that wearing polka dot socks increases test scores, even though this is not supported by the data.
