3.92
= 1.00 + 1.00 + 1.00 + 0.92
= 100/100 + 100/100 + 100/100 + 92/100
= 300/100 + 92/100
= 392/100
-------------------------------------------------------
392/100 = 196/50 = 98/25
Solution: We are given:
μ=180,σ=25,n=100
Therefore the standard error of the mean is



Answer:
See proof below
Step-by-step explanation:
We have to verify that if we substitute
in the equation
the equality is true.
Let's substitute first in the right hand side:

Now we use the distributive laws. Also, note that
(this also works when the power is n-2).



then the sequence solves the recurrence relation.
