guestton it 2 A researcher is interested in Whether people have experience damage to the prefrontal cortex preform as well on executive function and working memory tasks. Using the GolNo Go task, the general population (who have no damage to their brain) are normally distributed with a mean of 78 and a variance of 10. In the present study, however, the researcher arranges to test 100 people who had no sleep the previous night. The mean accuracy for these 100 individuals was 64. Using the .05 level, What should the researcher conclude? Carry out the run five steps at hypothesis testing for a twoitailed test. In step V, sketch the comparison distribution. Label the mean with both a Z and a raw score. Draw in the cut-ol't'(s) and label with Zscores. Label the percent of the area cutoff. Indicate the position of the sample mean and label it with both a Z and a raw score. Step 1: Population 1: Population 2: Research hypothesis: Null hypothesis: Stpp H: Give the characteristics of the comparison distribution Step 1]]: Give the cut-off sample score(s) Stpp IV: Determine the sample Zscore on the comparison distribution Stgp V: Sketch the comparison distribution and give the decision -Compute the 95% condence inter-mt
