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
