I Professor Brown administered an achievement test, which as he remembers from years of experience, yielded a population mean score of 85. If his class of 25 students obtained a mean score of 89 with standard deviation score of 14, can the professor claim that his class is a superior class? Assume that the mean score is approximately normally distributed. Use a = 0.01

= Scores on a standardized exam are known to follow a normal distribution with standard deviation o 8.2. A researcher randomly selects 100 students and computes their average score. He reports that the mean score is 83, with a margin of error of 1.436. How confident are you that the mean score for all students taking the exam is in the interval (81.564, 84.436)?
Acorns in the northern Atlantic regions of the U. S. have an average volume of 3.75 cubic centimeters, with a standard deviation of .85 centimeters. If we were to collect 1000 samples of 300 randomly-selected acorns, describe the sampling distribution for the sample mean of acorn volumes. Round to the nearest hundredth (two decimal places) if necessary. Shape: Center: Spread:
