Neco 2017 Geography Question 4

A weather station recorded the following maximum daily temperatures (°C) and relative humidities (%) for a consecutive seven‑day period. The wind speed was steady at 2 m·s⁻¹ throughout the week. | Day | Tmax (°C) | RH (%) | |-----|----------|--------| | 1 | 32 | 70 | | 2 | 34 | 65 | | 3 | 31 | 80 | | 4 | 35 | 60 | | 5 | 33 | 75 | | 6 | 30 | 85 | | 7 | 36 | 55 | The heat‑index (HI) for each day may be approximated by the formula: HI = T + 0.33·RH – 0.70·V – 4.00, where T is the maximum temperature (°C), RH is the relative humidity (%), and V is the wind speed (m·s⁻¹). Answer the following:
