(i) From the graph, we can observe that around 10 students like cooking.
(ii) 

• From the graph, it appears that Gardening is liked by 15 students.
• Photography is liked by 20 students.

To find how many more students like Gardening than Photography:

• Difference = Gardening (15 students) - Photography (20 students)
• The difference is 5 fewer students like Gardening than Photography.

Thus, 5 fewer students like Gardening compared to Photography.

(i) From the graph, it appears that 20 students like Hiking.
(ii) 

• From the graph, Camping is liked by 15 students.
• Bird Watching is liked by 10 students.
