The percent of students that are aged 19 years or more is determined as 84%.
<h3>One standard deviation below the mean</h3>
In a normal distribution curve 1 standard deviation below the mean is defined as follows;
- 1 std below mean : M - d = 16%
M - d = 20.6 yrs - 1.3 yrs = 19.3 years ≈ 19 years
19 years or more will occur at (M - d) + (M) + (M + 2d) = 100% - (M - d)
= 100% - 16%
= 84%
Thus, the percent of students that are aged 19 years or more is determined as 84%.

Step-by-step explanation:
20% as a decimal is 0.2
For each year get the amount of increase by multiplying the number of rabbits by 0.2
Rabbits in 2013:
25 x 0.2 = 5
25 + 5 = 30 rabbits
Rabbits in 2014:
30 x 0.2 = 6
30 + 6 = 36 rabbits
Rabbits in 2015:
36 x 0.2 = 7.2
36 + 7.2 = 43.2
Rabbits in 2016:
43.2 x 0.2 = 8.64
43.2 + 8.64 = 51.84
Rabbits in 2017:
51.84 x 0.2 = 10.368
51.84 + 10.368 = 62.208
= 62 rabbits
