Dr. Clark is interested in a new treatment for daily stress. She recruits a sample of $N=36$ students to participate in a study where they receive occasional positive affirmations received on their phones. Dr. Clark measures their stress level on a scale from 1 to 10 , which higher scores representing higher stress. In the general population, college students average a stress level of $?=6.2$. Dr. Clark's sample averaged a stress level of $M=5.6,s=2.9$. Is there sufficient evidence to conclude that $Dr$. Clark's stress intervention successfully reduced daily stress? Test using an .05 alpha level. Answer the following questions related to the research problem: Question 30 2 pts What is the dependent variable in the above research study, and what is the scale of measurement of that variable?
