Get two points and do change in y over change in x
for example
the 2 points are (2,4) (4,8)
change in y: 8-4= 4
change in x: 4-2=2
4/2= 2
Using the concepts of parameter and statistic, it is found that the correct option is:
- 2% is a statistic and 5% is a statistic.
<h3>Parameter and Statistic:</h3>
- If the information is taken from a sample, it is called a statistic.
- If the information is taken from a population, it is called a parameter.
In this problem, both percentages are taken from samples, hence both the 2% and the 5% represents statistics, and the first option is correct.

Answer:
The percentage increase in Jayana's postcard collection is 15%
Step-by-step explanation:
Jayana had 20 postcards last year
With 3 more postcards this year
From the given equation Quantity = Percent x Whole
Here;
Let P = Percent/100%
Quantity = Increment in postcard = 3 postcards
Whole = The total postcards from last year = 20 postcards
Hence,
3 postcards = P x 20 postcards
P = 3/20 = 0.15
Recall P = Percent/100%
∴ Percent = P x 100% = 0.15 x 100% = 15%
The percentage increase in Jayana's postcard collection is 15%
