I saw your writing '8', '4' and '2' on the temperature axis. For the 24.0 deg C, the point is around halfway between 2 and 4, so we can take it as 3 (after all, the 'days' in this question can be taken to be whole numbers).

(a) 24.0 deg C. There are 30 days in September and the total frequency is 30 (this seen in 3 + 5 + 8 + 7 + 4 + 2 + 1 = 30) and the lowest temperature seen is 24.0 deg C.
(b) 25.0 deg C. This is the most common temperature, seen in 8 of the 30 days.
(c) This is similar in working to questions such as calculating average speed given different journey speeds, distances and travel timings.
(d) 14 out of the 30 days have temperatures above 25 deg C, so we just express this in percentage form.
