Insufficient Data

For Case Study 1, In Q1 and Q3, it's been asked to calculate monthly throughput and monthly language percent share respectively. In Q2, it's been asked to calculate weekly average. In Q4, it's been asked to find duplicate rows. All this is fine, but the data itself has 8 rows and represents 6 days' data which has no duplicate records. Please advise on how to move forward with the questions.
