Test of independence of attributes

5. The following data resulted from an experiment to study the effects of leaf removal on the ability of fruit of a certain type to mature:

Treatment No of fruits matured No of fruits aborted
Control 141 206
Two leaves removed 28 69
Four leaves removed 25 73
Six leaves removed 24 78
Eight leaves removed 20 82

Does the data suggest that the chance of a fruit maturing is affected by the number of leaves removed? State and test the appropriate hypothesis.
