1. **Make a histogram of the data.** Describe the shape of the distribution.
2. **Use the summary statistics to calculate the percent of data values within 1, 2, and 3 standard deviations of the mean.** How closely do the results match the empirical rule?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8ac777f1-8186-4759-9220-5e0c4743beda%2Fa5614180-6384-4e68-9e67-648a38a1e7af%2Fb3tuhl_processed.jpeg&w=3840&q=75)
