taking the drug are healed within 8 weeks. In
clinical​ trials, 220 of 235 patients suffering from acid
reflux disease were healed after 8 weeks. Test
the​ manufacturer's claim at the α=0.05 level of
significance.
a. Because np01−p0=_____ is
[>,<,=,≠] 10, the sample size is
[>,<] 5% of the population​ size, and
the sample [can be reasonably assumed to be random is given
to be random, is given to not be random, cannot be reasonably
assumed to be random] the requirements for testing the
hypothesis ____ satisfied.
b. H0 [ ] [ ] [ ] versus
H1 [ ] [ ] [ ]
c. Now find (I don't know why that
symbol is so high)
d. Determine the statistic, z0
e. Find the P-value
