day	sun	mon	tues	wed	thurs	fri	sat

day	sun	mon	tues	wed	thurs	fri	sat

day	sun	mon	tues	wed	thurs	fri	sat

day	sun	mon	tues	wed	thurs	fri	sat

Explanation:

Step1: Analyze the bar graph's height relationships

From the bar graph, we observe the following approximate order of air pressure (from highest to lowest or by relative heights): Sun, Thurs, Wed are relatively tall (close to 770 - 780+), then Fri, then Mon, Tues, Sat (with Mon and Tues similar, Sat a bit lower than them).

Step2: Compare with each table

• First table: Sun (782), Thurs (785), Wed (779) are high. Fri (764), Mon (754), Tues (755) (Mon and Tues close), Sat (753) (lower than Mon/Tues). This matches the height relationships (Sun, Thurs, Wed tall; Fri moderate; Mon, Tues similar; Sat lower).
• Second table: Values are too rounded (780, 750, 760, etc.) and Wed (780) same as Sun (780) but graph shows Wed and Sun as similar but not exact, and Thurs is higher than Wed in graph, but here Thurs is 790 (too high relative to graph).
• Third table: Mon (759) and Tues (755) are not as close as graph (Mon and Tues bars look similar in height, 759 and 755 have a 4 difference, but first table has 754 and 755 (1 difference) which is better. Also Sat (758) is higher than Mon/Tues in this table, but graph shows Sat lower than Mon/Tues.
• Fourth table: Wed (774) and Thurs (775) are lower than Sun (782) but graph shows Wed and Thurs as tall as Sun, so this is incorrect.

Answer:

The first table (with Air Pressure values 782, 754, 755, 779, 785, 764, 753 for Sun to Sat respectively)
