Question 1: Airborne LiDAR (Light Detection and Ranging) data were collected over two areas in a catchment region using two different LiDAR sensors. Some GNSS data were also collected in both areas to assess the height accuracy of the LiDAR data. The GNSS and corresponding LiDAR-derived heights for each area are provided in the table below. All height values have been converted to the Australian Height Datum (AHD). Based on these datasets, is there a statistically significant difference in the height accuracy of the LiDAR data collected by the two different LiDAR sensors (using a significance level of a = 0.05)? Answer the question using a) The longhand approach. b) Using the Excel functions.
