Question

Two different species of trees have heights that are approximately normal in distribution. Tree A has a mean of 36 feet and a standard deviation of 3 feet. Tree B has a mean of 52 feet with a standard deviation of 7 feet. You can just copy your answers from stat key for parts A and B, or you can provide screenshots for possibly partial credit. Be sure to fully support your answer for part C.

a) What proportion of the species A trees are above 40 feet tall?
b) What proportion of the species B trees are less than 40 feet tall?
c) Suppose one tree of type A is 41.4 feet tall and one tree of type B is 62.1 feet tall. Which tree is taller relative to the species? For full credit fully support your answer with work or Stat Key output.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
