Answer:
1 point, (1.5,0)
Step-by-step explanation:
Inputting the equation into a graphing calculator (desmos) you can find the x intercept (where the line hits the x-axis)
We can solve this problem by using the formula:
s = σ / sqrt(n)
where,
s = standard deviation of the sample
σ = standard deviation of the population = 3 years
n = number of samples = 100
Substituting:
s = 3 years / sqrt (100)
s = 0.3 years (ANSWER)
