A medical researcher studied an SRS of 3500 cases of the flu and reported that she was 90% confident that the true proportion of people who recover from the flu within 2 weeks lies between 0.712 and 0.747. Which of the following gives a valid interpretation of the 90% level? a. 90% of people recover from the flu within 2 weeks.
b. If her study was repeated many times, 90% of the resulting confidence intervals would contain the true proportion of people recovering from the flu within 2 weeks.
c. Somewhere between 71.2% and 74.7% of people recover from the flu within 2 weeks. d. If her study was repeated many times, 90% of the sample proportions would lie between 0.712 and 0.747.
e. She's 90% confident that the average flu recovery time lies somewhere between 0.712 and 0.747 days.​
