1. copy the name and the age at inauguration for each
2. convert each age at inauguration in years plus days to decimal years to the nearest hundredths. (Divide the number of days by
365 and add the resulting decimal to the number of years. 43 years, 236 days = 43 + 236/365 = 43.65 years )
3. Find the mean, median, mode, range, Q1, Q2, Q3, and IQR for the data. Show all work and write a sentence that explains
how each statistic is calculated or determined.
4. Two of the above were not inaugurated on a January 20. Explain why in a couple of complete sentences.
