A survey was conducted to calculate the average height students at MNSU. It turns out that after asking every single student, the average height is 67.5 inches. Suppose just a few days before you obtained this mean, you took a sample of 200 students and constructed a confidence interval estimate of the average mean. Which of the following is true? The center of the interval will be 67.5 The interval will contain 67.5 O The confidence level used was 99% The z-score used for this interval is ± 1.96 O None of the above
