Step-by-step explanation:
Sampling

Here, the population of interest is all New York state residents.

Sample of 250 students at the University.
So the population of interest is all the students at the University, to find their parking times.
Answer:
Yes, in fact Bill exceeded his target by £2,200.
Step-by-step explanation:
Cost of the laptops = 50 x 400
= 20,000
Sold 40 at 30% profit
(40 x 400) x 1.30
= 20,800
Sold 10 at 15% profit
(15 x 400) x 1.15
= 6900
Total sales value
= 20800 + 6900 = 27,700
