I was to choose 30 hiking trails (15 from New Hampshire and 15from Maine) and record their elevations. My hypothesis for this isI believe that the mean is greater then or equal to 2,500ft. I'mhaving trouble figuring out my population mean and my sample mean.Also I need to find out my z score or t score and show a graphshowing whether its left or right tailed or both.
