Answer:
Option B) 19.1 years
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 9
Sample mean, = 19.1 years
Alpha, α = 0.05
Population standard deviation, σ = 1.5 years
We have to approximate best point estimate for population mean.
The best point estimate for population mean is the sample mean.
Thus, we can write
Thus, the correct answer is
Option B) 19.1 years
Answer:
2/5
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(5-7)/(-3-2)
m=-2/-5
m=2/5
Answer:
271/100.
Step-by-step explanation:
Using the modified Pythagorean equation sqrt((6-4)^2 + (2-(-2))^2 = c^2, you get the sqrt(4 + 16) or sqrt 20. Factor the 20 into sqrt(4x5) you get 2xsqrt(5)
