Suppose we are interested to construct a confidence interval of the mean exam score. A random sample of 36 scores is taken and gives a sample mean (sample mean score) of 68. We know that the population standard deviation is 3 points. EBM will be the largest a. for a 95% confidence level b. for a 90% confidence level c. for a 66% confidence level d. for a 99% confidence level
