A research team is developing an Al model to detect diseases from medical images. The model is expected to have an 95% accuracy in identifying a specific condition. On n = 13 randomly selected days, the model is tested with new medical images, and its accuracy is recorded. The results are given below. 95, 96, 99, 94, 98, 96, 96, 95, 97, 99, 95, 94, 94 These data can be found in column 2, starting in the 2nd row, of the Download.csv file Assume that the model's accuracy follows a Normal distribution from one test to the next.
