Question: Lastly, let's finish cleaning this dataframe. With the `apdata_valid_apscores` data frame you just created, use a Boolean operator to keep only rows with a PSAT score greater than 300. Any student with a PSAT score less than 300 was found to be a data entry error. (It happens!) Store this final data frame as `apdata_clean`. This data frame should have only the values 1 through 5 for the ACTUAL variable and values greater than 300 with no NAs in the PSAT scores variable in Rstudio and data set "apdata'
