1. draw a histogram from all the data. starting at the bottom row, for each set of 10 flips, place an "x" in the column
corresponding to the number of heads that set produced. your histogram should look similar to the example below:
number of heads in 10 flips
2. calculate the mean and standard deviation
mean = standard deviation =
3. calculate the percent of the data that is within 1, 2, and 3 standard deviations of the mean.
_%
1. within 1 standard deviation =
2. within 2 standard deviations =
3. within 3 standard deviations =
4. compare your results to a normal distribution. interpret any differences.

The height of a birch tree, f(x), in inches, after x months is shown in the graph below. how much does the birch tree grow per month, and what will be the height of the birch tree after 10 months? a. the birch tree grows 1 inch per month. the height of the birch tree will be 16 inches after 10 months. b. the birch tree grows 2 inches per month. the height of the birch tree will be 26 inches after 10 months. c. the birch tree grows 3 inches per month. the height of the birch tree will be 36 inches after 10 months. d. the birch tree grows 2 inches per month. the height of the birch tree will be 24 inches after 10 months.
