Chi-squared analysis for drug trial data?

Null hypothesis – The number of people in Group A with healed wounds is equivalent to the number of people in Group B with healed wounds.

Drug trial data -

Recently a clinical drug trial was carried out on a new anti-HIV treatment which increases the rate of healing of ’seeping wounds’ of AIDS sufferers. The medical biologists carrying out the trial implemented a ‘double-blind’ test. A total of 400 people were subjected to the trial, with two groups of equal-size for each medicine. 200 of group A were given the new drug, X, while 200 of group B were given an existing drug, Y.
At the end of 7 days everyone was assessed.
It was found that 24 of those in group A had their wounds healed.
It was found that 14 of those in group B had their wounds healed.

Can anyone based on my null hypothesis do the chi-squared analysis for the drug trial data above?
