Can you check if this problem is correct. So I did a survey that was"On average, how many hours of music do you listen to per day?". So to find the weekly average, I multiplied each interval by 7. In the United states, the average weekly time is 26.90 hours per week. These were my results. Please check if my math is right, if its left tailed, is the hypothesis null or not, and create the hypothesis.
