Answer:
Sampling Error
Step-by-step explanation:
When the researcher randomly selected 200 people, he is creating an sample or subset from the population, that would be all the people in the earth. The error obtained was product of the fact that the analysis he made was estimated from the sample and not the whole population. There is no other mentioned factor that could cause an error, so the answer would be a sampling Error.
Answer:
$424
Step-by-step explanation:
Find area of all surfaces to be covered
20 x 30 = 600 ceiling
10 x 20 = 200 x 2 = 400 two walls
10 x 30 = 300 x = 600 other two walls
Assume no doors
total area is 1600 square feet
multiply by 2 because you are doing two coats
3200 total area to be covered
3200/400 = 8 gallons of paint x $53 = $424
