Since last (day of the week), about how many hours did he/she do this work?
Warning: these figures indicate the number of cases found in the data file. They cannot be interpreted as summary statistics of the population of interest.
Insert the estimated number of hours worked. Again, make sure the mother/primary caretaker understands what you mean by 'since last (day of the week)' - specify the name of today's weekday, just as you did for CL4 and CL7.
