A research study was conducted to examine if a new antidepressant could lower depression for depressive adults. One sample of 10 depressed patients participated in this study. You have been given the information about the sample 10 and the population mean=33, standard deviation=5). After taking this new antidepressant are the depression scores of this sample of 10 patients significantly lower than the population’s depression scores? Complete all the steps to test the null hypothesis if: n= sample size = 10 μμ = population mean= 33 σσ = population sd = 5 x⎯⎯x¯ = sample mean = 30 αα = 0.05 = level of significance Test the null hypothesis at the .05 alpha level. What type of error might you have made if you rejected the null hypothesis?
