Vicks VapoRub is considered absolutely unsafe for children under 2. Consumption of small amounts of one of the ingredients (camphor) can be fatal for children, and getting Vicks in your eye (hard to avoid in little ones) can cause eye damage. So, I would highly recommend against using it in young children.

For 1-proportion z tests, we will round the z-test statistic to 4 decimal places and the P-value to 3 significant figures; these are the same rounding rules your TI-83/84 calculator typically uses in Draw mode. However, be aware that your calculator sometimes rounds very low P-values to 0 in Draw mode.
