The `iris' data set consists of 50 samples from each of three species of Iris (Iris setosa, Iris virginica and Iris versicolor). Four features were measured from each sample: the length and the width of the sepals and petals, in centimeters. Below is the sepal length of Iris setosa and Iris virginica.

2. Find the area of the region bounded above by $y = x + 20$, below by $y = \frac{1}{x}$, and bounded on the sides by $x = 1$ and $x = 2$. (20 points) 3. $f(x) = \frac{x+1}{x}$ Find the average value of $f$ over the interval $[1, e]$ (20 points)
A group of scientists determines that a mitochondrial DNA sequence shared by two species has a constant mutation rate. The sequences of mitochondrial DNA for the two species are shown below. Species A: GACTGGGCATTA Species B: GACCGGACATTA Based on this information, which of the following best explains the difference in the DNA sequence between the two species? Species A and B probably share the most recent ancestor because they only differ by three mutations. Species A and B have fewer differences between DNA sequences means that fewer mutations occurred. Species A and B probably have distinct ancestors because they have many differences in mutations. Species A and B are closely related because they differ by five mutations in their DNA sequence.
