12. The "Factor_D" variable contains 15 unique values (i.e. 10, 15, 20, 21, ..., 85, 90). There is at least one single observation where `Factor_D = 26` (possibly more). Assume these observations were improperly recorded and, in fact, the value should be 25.
12. The "Factor_D" variable contains 13 unique values (i.e. 10, 15, 20, 21, ..., 70, 90). There is at least one single observation where `Factor_D = 26` (possibly more). Assume these observations were improperly recorded and, in fact, the value should be 25.

Using `ifelse()` (or __dplyr__'s `if_else()`) inside `mutate()`, recode any values where `Factor_D == 26` to be 25.
