A statistical statement is the one that deals with a group of data that is collected from a population or a sample population.
Here when you look the statements B,C and D, you can see that it mentions a group of people or data like time, number etc.
But the statement A does not deal with the population, but it deals with one single person who won the competition. Hence this is the statement that is not statistical
Answer:
69.81 sq. m. (rounded to 2 decimal places)
Step-by-step explanation:
The sector of a circle is "part" or "portion" of a circle. The formula for the area of a sector is:

Where
is the central angle
r is the radius
Given the figure, the arc is given as 80 degrees, but not the central angle of the shaded sector. But from geometry we know that the central angle and the intercepted arc have the same measure. So we can say:

Also, the radius of the circle shown is 10 meters, so
r = 10
Now, we substitute in formula and find our answer:

Thus,
The area of the shaded sector is 69.81 sq. meters.
