The vector `problem.1.data` contains numeric data.
Construct a stipchart of the values in `problem.1.data`. Do you see any evidence of any outliers?
**Solution**
Repair this outlier.
* First, report the location of the outlier.
* Next, convert the value to `NA`.
* Finally, display the value of the vector at this location, and show that it has the value `NA`.
**Solution**
Construct a stripchart of the repaired version of `problem.1.data`. Do you see any indication of a -9 being used to represent a missing value?
**Solution**
It’s not best practice to represent a missing value using the value -9, so we need to repair this.
* First, report the location of the element with -9.
* Next, convert the value to `NA`.
* Finally, display the value of the vector at this location, and show that it has the value `NA`.
**Solution**
Construct a stripchart of the repaired version of `problem.1.data`. Do you see any indication of an extreme outlier (i.e. 99999) or a -9 being used to represent a missing value?
