A tree farmer wants to estimate the average height of the spruce tree saplings that are growing on the farm. The distribution of heights of all tree saplings on the farm is approximately Normal. The farmer selects a random sample of 18 trees and measures their heights. The farmer would like to construct a 95% confidence interval to estimate the true height of the sapling spruce trees on the farm. Identify if the conditions for computing a confidence Interval for a population mean are met.
a. Random condition: _____.
b. 10% condition: ______.
c. Normal/Large Sample condition: ______.
d. Are all the conditions for inference met? _____.
