A research study reported a 95% confidence interval for the mean time of hip surgeries based on a sample of 91 patients as (116 minutes, 138 minutes). Which of the following statements is correct about the given interval? A. Correct B. Incorrect - We are 100% sure that the mean time of hip surgeries of the sampled 91 patients is between 116 and 138 minutes. -95% of the hip surgeries of the sampled 91 patients will fall between 116 and 138 minutes. We are 100% sure of hip surgeries take between 116 and 138 minutes. We are 95% sure that hip surgeries will take, on average, 116 to 138 minutes.
