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
x
4
x x
5 6
x
7
x
8
0
1 2
3
9 10
flo set
number of heads in 10 flins
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.
