Scores on a standardized exam are known to follow a normal distribution with a standard deviation of \( \sigma = 8 \). A researcher randomly selects 84 students and finds their mean exam score to be \( \bar{x} = 78 \). How confident are you that the mean score for all students taking the exam is in the interval (76.702, 79.298)?*Include 2 decimal places in your final answer*Confidence Level: [Text box for input]
