Doctors believe that 80% of people properly complete their antibiotic prescriptions. After an education
campaign, they hope that this will improve.
Use a significance level of a =
= 0.01.
In a random sample of 185 patients, 160 of them properly completed their antibiotic prescriptions.
Note: Be sure to use at least four decimal places in all intermediate calculations.
State the hypotheses of this test.
O Ho p=
О Но:р - 0.8649
O Ho:p = 0.8
HA:P + 0.8
HA:P 0.8649
O Ho:p = 0.8
HA:P < 0.8
O Ho:p 0.8649
HA:P < 0.8649
O Ho:p = 0.8649
HA P> 0.8649
О Но:р - 0.8
Ho:P
HA:p > 0.8
Define the parameter of interest in full context.
p is the number of patients that complete their antibiotic prescriptions, of all patients.
p is the sample proportion of these 185 patients that completed their antibiotic prescriptions.
p is the population proportion of all patients that complete their antibiotic prescriptions.
Op is the population proportion of the 185 patients that completed their antibiotic prescriptions.
