Round your answer to three decimal places. Type your answer below. QUESTION 7 Out of 190 randomly selected adults in the U.S. who were surveyed, 71 excercise on a regular basis. A 95% confidence interval is found to be (0.305, 0.442) Interpret the confidence interval. o We can say with 95% confidence that the proportion of all adults in the US who excercise on a regular basis is between 0.305 and 0.442 (or between 30.5% and 44.2%). We can say the proportion of all adults in the US who excercise on a regular basis is between 0.305 and 0.442 (or between 30.5% and 44.2%). O We can say the proportion of all adults in the US who excercise on a regular basis is between 0.305 and 0.442 (or between 30.5% and 44.2%) is 95%. O We can say 95% of all adults in the US who excercise on a regular basis between 0.305 and 0.442 (or between 30.5% and 44.2%).
