Suppose you work for a pharmaceutical company that is testing anew drug to treat ulcerative colitis. You conduct a random sampleof 31 patients on the new drug and 10 of them indicated a decreasein symptoms since starting the drug regimen. You construct a 95%confidence interval for this proportion to be ( 0.158 , 0.4871 ).What is the correct interpretation of this confidence interval?
Question 9 options:
| 1) | We are 95% confident that the proportion of all patients on thedrug regimen that have experienced a reduction in symptoms isbetween 0.158 and 0.4871. |
|
| 2) | We are 95% confident that the proportion of patients surveyedthat have experienced a reduction in symptoms is between 0.158 and0.4871. |
|
| 3) | We are certain that 95% of patients will be between 0.158 and0.4871. |
|
| 4) | We cannot determine the proper interpretation of thisinterval. |
|
| 5) | We are 95% confident that the proportion of patients who shouldbe on this drug is between 0.158 and 0.4871. |
