A school psychologist wants to perform a study at a local elementary school where 150 students that have long-term concentration issues. The purpose of the study would be to determine if doing jumping jacks for 5 minutes helps with long-term concentration compared to sitting still for 5 minutes. Part A: Describe an appropriate design for the study. (5 points) Part B: The hypotheses for this study are as follows: H0: There is no difference in the mean improvement of long-term concentration for either treatment. Ha: The mean improvement of long-term concentration is greater for the jumping jacks treatment. The school will allow students to do jumping jacks during class if the null hypothesis is rejected. What are the possible Type I and II errors? Describe the consequences of each in the context of this study and discuss which type you think is more serious. (5 points)

Graph a sine function whose amplitude is 3, period is 4π , midline is y = 2, and y-intercept is (0, 2) . the graph is not a reflection of the parent function over the x-axis. use the sine tool to graph the function. the first point must be on the midline and the second point must be a maximum or minimum value on the graph closest to the first point.
