Dr. Smile is interested in evaluating whether 7-year-old autistic children differ from the general population of 7-year-old children in their ability to recognize facial expressions. She develops the Facial Recognition Test, which has mean = 200 among the general population of 7-year-olds. Dr. Smile collects data on a sample of 16 children with autism. In this sample Xbar = 180 and s = 12.

A) using alpha= 0.05 and a two-tailed test, conduct a one-sample t-test evaluating the null hypothesis.

b) based on these results, should Dr Smile reject or fail to reject the null hypothesis?

c)Report the resukts of the hypothesis test you conducted in part B as if Dr Smile were writing about them in a journal article.

Question Dr. Whistle was interested in evaluating whether her therapy for post-traumatic stress disorder (PTSD) was effective for treating a group of trauma (abuse) survivors.
