A random sample of 36 students at a community college showed an average age of 25 years. Assume the ages of all students at the college are normally distributed with a standard deviation of 1.8 years. The 98% confidence interval for the average age of all students at this college is ________________________. Refer to the following formula and table. σ x   =   σ n z = x – μ σ x Standard Error = σ n Margin of Error = z α / 2   *   σ n Confidence Interval = x   ±   z α / 2 * σ n z dsistribution table from 0.0 to 2.49.jpg
