I am not sure if I can compare the measurments fro the above study with the standard normal distribution. I feel like I do not have enough data. Am I right or is it the standard normal distribution ?

Question

Medication at the end of life
During the last month of life, residents were prescribed
a mean of 7 (range 1–12) regular oral/
trans-dermal/per-rectal medications. Of the
48 residents, 58% (n=28) received a regular analgesic
preparation during this time and 63%
(n=30) were given antibiotics. A range of PRN
(as necessary) medications were additionally
given. The most frequently administered PRN
medications were analgesics (n=18) and oxygen
(n=6). Despite the occasional use of assessment
tools, the symptom control issues of some residents
persisted.
As their condition deteriorated, 46% (n=22) of
residents had their regular medication reviewed
and either all, or some, of their oral, transdermal,
per-rectal medications discontinued. However,
provision and administration of medication in
NCHs varied considerably. In NCH-A, for example,
the GP reviewed residents regularly, there
was recognition when residents were dying, information
was well recorded, residents’ relatives
were contacted and the situation discussed with
them and the full nursing team. Even though
preparations were changed to liquid, no injectable
medication was prescribed in anticipation of
the resident becoming unable to swallow. In contrast,
in NCH-D, nine out of 10 residents were
prescribed injectable medication for symptom
control when they became unable to swallow
their oral medication.

Thank you.
