Lea knows the following information about the 50 days
where she tracked whether she wore a tie and whether
she received a compliment on her outfit:
•
There were 11 days where she neither wore a tie nor
received a compliment.
•
There were 30 days in total where she received a
compliment.
•
There were 16 days in total where she did not wear a
tie.
Can you help Lea organize the results into a two-way
frequency table?
Wore a
tie
Did not wear a
tie
Recelved a compliment
Did not receive a
compliment
