Suppose that the lengths, in inches, of adult corn snakes are normally distributed with an unknown mean and standard deviation. A random sample of 38 snakes is taken and gives a sample mean of 51 inches and a sample standard deviation of 8 inches. The margin of error, for a 95% confidence interval estimate for the population mean using the Student's t-distribution is determined to be 2.63. Find a 95% confidence interval estimate for the population means using the Student's...
