Answer:
33.3%
Step-by-step explanation:
1. Formula: difference/original
2. 120 - 80 = 40
3. 40/120
4. 1/3
5. 1/3 = 33.3%
The common difference is (1,0.38).
An arithmetic progression (AP) is a sequence where the differences between every two consecutive terms are the same. In this type of progression, there is a possibility to derive a formula for the nth term of the AP. For example, the sequence 2, 6, 10, 14, … is an arithmetic progression (AP) because it follows a pattern where each number is obtained by adding 4 to the previous term.
x1 = 1 , y1 = 24
x2 = 2, y2 = 24.38
x3 = 3 , y3 = 24.76
x4 = 4 , y4 = 25.14
Thus the common difference equals :-
x2 - x1 = x3 - x2 = x4 - x3 = 1
y2 - y1 = y3 - y2 = y4 - y3 = 0.38.
Thus the common difference is (1,0.38).

Answer:
Statistical sampling is drawing a set of observations randomly from a population distribution. ... By repeating the sampling operation a large number of times, perhaps 1000, we decrease the sampling error and increase the quality of the estimates.
