A therapist wanted to determine if yoga or meditation is better for relieving stress. The therapist recruited 100 of her high-stress patients. Fifty of them were randomly assigned to take weekly yoga classes, and the other 50 were assigned weekly meditation classes. After one month, 30 of the 50 patients in the yoga group reported less stress, and 35 of the 50 patients in the meditation group reported less stress. Assuming the conditions for inference are met, what is the 95% confidence interval for the difference in proportions of patients experiencing stress relief from the yoga and meditation groups?

Question
A therapist wanted to determine if yoga or meditation is better for relieving stress. The therapist recruited 100 of her
high-stress patients. Fifty of them were randomly assigned to take weekly yoga classes, and the other 50 were
assigned weekly meditation classes. After one month, 30 of the 50 patients in the yoga group reported less stress,
and 35 of the 50 patients in the meditation group reported less stress. Assuming the conditions for inference are
met, what is the 95% confidence interval for the difference in proportions of patients experiencing stress relief from
the yoga and meditation groups?
