Question

Suppose you have a tree farm and you have 1000 live oaks on this farm. You are wondering if this would be a profitable time to harvest the tallest ones – those over 55 feet tall. Your sample of 100 of them indicates that their average height is 45 feet and that the standard deviation (s) of their heights is 5 feet. How many trees in your farm to you predict will have a height greater than 55 feet? (For this answer you do not need to provide a written explanation – simply provide the final answer and show enough of your work to earn part credit if your final answer is wrong. If you can simply provide a written explanation of your math that will be acceptable too.).

Explanation / Answer

T table = x-u/(s/squareroot n)

X is the sample mean

u is population mean

S is standard deviation

Sample size is n

T=55-45/(5/10)

T= 20/(1/2)

T=40
