Yes, it is possible to get three different values for the same statistics.
In statistics, the population is the pool of individuals from which a statistical sample is drawn for a study or for analyzation of the data and the numerical values which are obtained from the data is known as statistics. The measurement of sample is known sample statistics.
Now according to the question we have been given that there are three different samples of same size from a set of population. So data collected from these three different samples may be different that is it may vary from samples to samples. Therefore corresponding sample statistic will also vary sample to sample.
Hence , it is possible to get three different values for the same statistics.

Answer:
Parking lot is 60m wide
Step-by-step explanation:
In this question. We are asked to calculate the width of the parking lot. We proceed as follows:
We know that the total length of the field and the parking lot is 300m while the total width is 200m. We should remember that the field is rectangular in nature.
Since the parking lot is x meters, the length of the field would simply be (300-2x)m while the width of the field would be (200-x). The width would also have been 200-2x but we must remember that the field is only covered on 3 sides.
Area of the field is 30,000. This means if we multiply both, we get 30,000.
Mathematically;
(300-2x)(200-x) = 30,000
60,000-300x-400x+ 2x^2 = 30,000
2x^2-700x-30,000= 0
We can see we now have a quadratic equation we need to solve.
2x^2+500x-1200x-30,000= 0
2x(x+250) -120(x+250) = 0
(2x-120)(x+250) = 0
2x-120= 0 or x+250=0
2x = 120or x = -250
x = 120/2 or x= -250
x = 60 or x=-250
We discard x = -100 as x is length and cannot be negative
Hence, x = 60m
