Alright, this is a conceptually tough one, if you are not very good with recognizing conjugate species. As I suspect, you know that ammonia and ammonium are related. The relationship is that the ammonium is the conjugate acid of ammonia.

They are related by one hydrogen ...

Medical Blood Plasma. Let x be the variable that represents the pH of the arterial plasma (i.e. acidity of the blood). For healthy adults, the mean of the x distribution is = 7.4. A new drug for arthritis has been developed.

Medical Blood Plasma. Let x be the variable that represents the pH of the arterial plasma (i.e. acidity of the blood). For healthy adults, the mean of the x distribution is = 7.4. A new drug for arthritis has been developed. However it is thought that this drug may change blood pH. A random sample of 31 patients with arthritis too the drug for 3 months. Blood tests show the average pH to be xbar = 8.1 with a sample standard deviation s = 1.9. Use a 5% level of significance to test the claim that the drug has changed (either way) the mean pH level of blood.
