Hye sir can you help me to solve it.

QUESTION 1 The following table shows the concentration of particulate matter (PM2.5) and wind velocity recorded at an air quality monitoring station. Wind speed (m/s) PM2.5 (ug/m3) 5.42 69.2 4.94 59.2 4.33 79.2 4.72 79.2 4.06 59.6 4.06 72.4 3.17 53.2 2.94 50.0 2.81 46.8 3.14 51.6 Calculate: i. Sample mean, median and mode. ii. Standard deviation. iii. Correlation coefficient (r) and give comment. iv. Fit a least square line that will enable to predict the PM2.s in terms of wind speed. Interpret the results. V. Estimate the concentration of PM25 when the wind speed is 4.50 m/s
