A psychologist conducted a study to investigate the effectiveness of two different therapy approaches (Approach A and Approach B) in reducing symptoms of anxiety disorder. Two independent samples were taken: 527 participants were randomly assigned to Approach A, and 558 participants were assigned to Approach B. After 8 weeks of therapy, participants were assessed for the presence or absence of clinically significant reduction in anxiety symptoms. The results showed that 365 participants in Approach A and 403 participants in Approach B showed clinically significant improvement. Perform a hypothesis test to determine if there is sufficient evidence to conclude that the proportion of participants showing clinically significant improvement with Approach A is lower than with the Approach B. In other words, the Approach B is more effective n reducing symptoms of anxiety disorder. Use a significance level of α = 0.10. Let parameter 1 represents the assessment results from the group of participants who were assigned to Therapy Approach A for the presence or absence of clinically significant reduction in anxiety symptoms, and parameter 2 represents the assessment results from the group of participants who were assigned to Therapy Approach B for the presence or absence of clinically significant reduction in anxiety symptoms. For this study, we should use a. z test for the difference between two population proportions b. t test for population mean c. z test for population proportion d. t test for the difference between two dependent population means e. t test for the difference between two independent population means
