Please answer the following question. I was confused if the answer is option A or C. Please read the options carefully.

Interpret the given condence interval. A study was conducted to determine if patients recovering from knee surgery should receive physical therapy two or three times per week. Suppose p3 represents the proportion of patients who showed improvement after one month of therapy three times a week and p2 represents the proportion of patients who showed improvement after one month of therapy twice a week. A 95% condence interval forpa -p2 is (0.16, 0.38). Give an interpretation of this condence interval. (6) We are 95% condent, based on the data, that the proportion of patients who show improvement with therapy three times per week is between 16% and 38% higher than the proportion who show improvement with therapy twice a week. 0 We know that 95% of all knee-surgery patients will show between 16% and 38% more improvement with therapy twice a week instead of three times per week. 0 We are 95% condent, based on the data, that patients who receive therapy three times per week show between 16% and 38% more improvement after one month than patients who receive therapy twice a week. 0 We are 95% condent, based on the data, that the proportion of patients who show improvement with therapy three times per week is between 16% and 38% lower than the proportion who show improvement with therapy twice a week. 0 We know that 95% of all knee-surgery patients will show between 16% and 38% more improvement with therapy three times per week instead of twice a week
