(6) A grad student is performing a study on a drug. He conducts a non directional hypothesis and conduct a two tailed test. Average score for all psychotic people is 100 with a standard deviation of 14. The sample of 49 psychotic people who tried out the new drug scored an average of 95.1. The alpha level is 0.01. With this knowledge, please answer all questions in the picture below (4 answers total should be provided). Please show work for answers.

The critical z-scores (the values for z-scores that separate the tails from the main body of the distribution, forming the critical regions) are 42.576 Calculate the z statistic, and use the Distributions tool to evaluate the null hypothesis. The z statistic is . The z statistic Ire in the critical region for a two-tailed hypothesis test. Therefore, the null hypothesis is Grade It Now Save & Continue Continue without saving
