Calculate for the mean/ average of the given numbers:
μ = (1 + 2 + 3 + 4 + 5) / 5 = 3
Then, we calculate for the summation of the squares of differences of these numbers from the mean, S
S = (1 - 3)² + (2 - 3)² + (3 - 3)² + (4 - 3)² + (5 - 3)²
S = 10
Divide this summation by the number of items and take the square root of the result to get the standard deviation.
SD = sqrt (10 / 5) = sqrt 2
SD = 1.41
Thus, the standard deviation of the given is equal to 1.41.

Step-by-step explanation:
Answer:
8
Step-by-step explanation:
Exponential decay is expressed by an equation of the form:
A = P(1 - r)^t
where P = initial value, r = annual rate of decay, t = time in years
A = 200(1 - 0.80)^2
A = 8
