This assignment for PSYC 2525 delves into hypothesis testing using Z-tests, covering both two-tailed and one-tailed tests. It includes the formulation of null and alternative hypotheses, calculation of areas under the normal curve, and determination of Z-scores. The assignment further examines Type I and Type II errors, defining statistical power and its formula. Practical application is demonstrated through computing Z-scores for given values based on a sample mean and standard deviation. Finally, the solution calculates a one-sample Z-test, determining the null and alternative hypotheses, standard error of the mean (SEM), and conducting the test at a specified significance level.
