Question

The mean temperatures in the first week of February were recorded as:
${18}^{\circ }C,{20}^{\circ }C,{25}^{\circ }C,{24}^{\circ }C,$${21}^{\circ }C,{24}^{\circ }C,{23}^{\circ }C$.
Find the approximate average temperature of the given week in ${}^{\circ }C$.

• A. $20$
• B. $24$
• C. $22$
• D. $23$

Answer 1

The correct option is C $22$

Number of days, $n=7$
The average will be the sum of the temperatures of all days divided by the number of days. Hence, average is:
$A=\frac{(18+20+25+24+21+24+23)}{7}$
$A=\frac{155}{7}$
$A={22.14}^{\circ }C\approx {22}^{\circ }C$
