Suppose that the scores for the ACT exam in a given year are normally distributed with an unknown μ{“version”:”1.1″,”math”:”μ”} and σ=3{“version”:”1.1″,”math”:”σ=3″}. A random sample of 36 exams has a mean of x¯=24{“version”:”1.1″,”math”:”x¯=24″} and a standard deviation of s=2{“version”:”1.1″,”math”:”s=2″}. Choose the distribution that could be used to find the 90% confidence interval for μ{“version”:”1.1″,”math”:”μ”} and determine how to calculate the error bound on the mean (EBM).
