A group of athletic therapists conduct a study of the effectiveness of a new type of therapy used to treat injured athletes. A sample of 120 injured athletes who were expected to remain on the disabled list for an entire season as a result of their injuries had their injuries treated using the new type of therapy. Of those athletes, 20 were cleared to return to playing without restrictions earlier than expected. Calculate the margin of error for this result at the 20% level of significance, and construct the corresponding confidence interval for the true proportion of athletes treated using the new type of therapy who will be cleared to return to playing without restrictions earlier than expected. Standard Normal Distribution Table E= Round to four decimal places if necessary Enter 0 if normal approximation cannot be used < p < Round to four decimal places if necessary Enter 0 if normal approximation cannot be used
