The weather station at Umuahia recorded the following data over five consecutive days: | Day | Max Temp (°C) | Min Temp (°C) | Relative Humidity (%) | Wind Speed (km/h) | |-----|---------------|---------------|-----------------------|-------------------| | 1 | 32 | 22 | 70 | 12 | | 2 | 35 | 24 | 80 | 8 | | 3 | 30 | 20 | 60 | 15 | | 4 | 33 | 23 | 75 | 10 | | 5 | 31 | 21 | 65 | 5 | The heat‑index (HI) for a day can be approximated by the formula: HI = T + 0.33 × RH – 0.70 × V – 4.00 where T is the mean daily temperature (°C), RH is the relative humidity (%), and V is the wind speed (km/h). Using the data above, answer the following:

( a )

Calculate the mean daily temperature for each of the five days.

( b )

Using the heat‑index formula provided, compute the heat‑index for each day and identify the day on which the heat‑index is highest.

( c )

Explain briefly why wind speed is included in the heat‑index calculation and how it affects the perceived temperature.

( d )

Suggest one precaution that residents should take on the day with the highest heat‑index.
