Answer 1

The correct option is C

4
The average of all the temperatures is:

$=\frac{Sumofallobservations}{Totalnumberofobservations}$

$Average=\frac{42+41+40+39+35+38+37}{7}$

$Average=38.8$ degree celsius

Therefore, on 4 days i.e., Monday, Tuesday. Wednesday and Thursday, the temperature is higher than the average.
