To estimate the new tree diameter in a forest a part in this and looked at a random sample of jeans from a representative section of a forest and measure them to determine the average diameter the park ranger knows that the distribution of samples means is given by a normal curve given that the same for me is 8.0 interest and a standard deviation of the sample means is 2.0 interest what is the probability that the main diameter of the trees in the section of forest is between 6.0 and 10.0 inches
