Statistics: A large math class receives exam grades. No information is given about the distribution of grades. A random sample of 25 grades has mean 25 and standard deviation s=10. Find a 95% confidence interval for the unknown population mean. Because no information about the distribution of grades is given, we invoke Chebyshev's Theorem.
