Scores on a standardized exam are known to follow a normal distribution with standard deviation σ = 21. A researcher randomly selects 125 students and computes their average score. He reports that the mean score is 73.8, with a margin of error of 2.920. How confident are you that the mean score for all students taking the exam is in the interval (70.88, 76.72)?
Below is a graph of a normal distribution with mean u = -3 and standard deviation o =2. The shaded region represents theprobability of obtaining a value from this distribution that is between -4 and 0. Shade the corresponding region under the standard normal curve below.
