Question:
Academy qualifying times for the mile run have been steadily decreasing through the years. The current average is 5.4 minutes with a standard deviation of 0.45 minutes. Find the 95% confidence level for acceptable qualifying times. Explain what these results mean (using sentences). Assume n = 25 times. And, since we don’t care if people run quicker, we need to make this one-tailed.
