Because npo (1- Po)
7.2 > 10,
= 187.2
the sample
size is
less than
5% of the population size, and the sample
can be reasonably assumed to be random,
the requirements for testing the hypothesis
are
satisfied.
(Round to one decimal place as needed.)
What are the null and alternative hypotheses?
Ho:
versus H,:
(Type integers or decimals. Do not round.)
