The daily minimum temperature recorded (in degree F) at a place during a week was as under:

Day	Temperature (°F)
Monday	35.2
Tuesday	31.1
Wednesday	27.6
Thursday	31.8
Friday	29.3
Saturday	23.8

Find the mean temperature.

We know that,

Mean = $\dfrac{\text{Sum of temperatures of all days}}{\text{Number of days}}$

= $\dfrac{35.2 + 31.1 + 27.6 + 31.8 + 29.3 + 23.8}{6}$

= $\dfrac{178.8}{6}$

= 29.8 °F

Hence, mean temperature = 29.8 °F.
