Explanation / Answer

Question 5:

The total number of patients is computed here as the sum of the number of patients across the 7 days computed as:

1187 + 755 + 1085 + 1031 + 1024 + 808 + 773= 6663 which is the correct figure given in the tables.

The percent of patients in the last column is computed as:

= Number of patients / Total number of patients multiplied by 100.

Therefore we compute it for each of the 7 days as:

Sunday: (1187 / 6663)*100 = 17.8%
Monday: (755 / 6663)*100 = 11.3%
Tuesday: (1085 / 6663)*100 = 16.3%
Wednesday: (1031 / 6663)*100 = 15.5%
Thursday: (1024 / 6663)*100 = 15.4%
Friday: (808 / 6663)*100 = 12.1%
Saturday: (773 / 6663)*100 = 11.6%

Therefore the percentage figure needs to be corrected for Sunday and thursday
