Question

What is the average weekly temperature of Siachen if the temperatures for each day are as follows :

- ${11}^{\circ }$ , - ${16}^{\circ }$ , - ${12}^{\circ }$ , - ${8.5}^{\circ }$ , - ${14}^{\circ }$ , - ${17.5}^{\circ }$ and - ${15.5}^{\circ }$

• A. - ${12.75}^{\circ }$
• B. - ${14.5}^{\circ }$
• C. - ${13}^{\circ }$
• D. - ${13.5}^{\circ }$

Answer 1

The correct option is D

- ${13.5}^{\circ }$

The average weekly temperature is given by : $\frac{Sumoftemperatures}{Totalnumberofsample}$

= - ($\frac{11+16+12+8.5+14+17.5+15.5}{7}$)

= - ($\frac{94.5}{7}$)

= - ${13.5}^{\circ }$
