1000, it's a simple division problem. 30,000 divided by 30.
The best approach to this is to use the formular
Standard error = standard deviation / sqrt( sample size)
standard deviation = 0.75 hours
sample size = 35
Hence, Standard error = 0.75 /sqrt(35) = 0.126 = 0.13
A(n)=A(n-1)+17 with A(1)=3
What is inside the parentheses can also be written as a subscript.
Hope this helps!
