Q$5$b: Update the $`$FRTDAY$`$ column in the dataframe $`$brf$\_$part$1`$ by removing the respondents who said "don't know$/$not sure" or refused to respond. Drop the original fruit variable from the $`$brf$\_$part$1`$ dataframe $($but keep FRTDAY$).$ Store the first $10$ rows of the dataframe as $`$Q$5.`$

Hint: The resulting dataframe is $422,747$ x $3.$ Be sure the variables are in this order $($left to right$)$: FRTDAY, the length of time variable, then the general health variable.
