A car owner conducts an experiment by filling up their car with 10 gallons of gas and drives until it runs out of gas. The number of miles driven from the 10 times of doing this experiment is shown below:
275 240 303 243 259 187 311 276 251 263
Find the following: Show ALL necessary work
a) Median
b) Lower and Upper Quartiles
c) IQR
d) State the mild outliers, if any. If there are no outliers, then state "no outliers".

John performs a similar colligative property experiment as Exp 22. He prepared a solution by mixing 11.2 g of naphthalene, C10H8(s), in 350.0 g of cyclohexane.If John measured the freezing point of this solution to be 1.28 celsius, what is the relative error in John's experiment?
| Molar mass | Freezing Point | Freezing Point Depression | |
| Cyclohexane | 84.16 g/mol | 6.55 celsius | 20.20 celsius/m |
| Napthalene | 128.17 g/mol | 80.26 celsius | 6.80 celsius/m |
