Determine whether a normal sampling distribution can be used for the following sample statistics. If it can be used, test the claim about the difference between two population proportions p1 and p2
at the level of significance α. Assume that the samples are random and independent. Claim: p1≠p2, α=0.01
at the level of significance α. Assume that the samples are random and independent. Claim: p1≠p2, α=0.01
Sample Statistics:
x1=36,
n1=75,
x2=38,
n2=65
Determine whether a normal sampling distribution can be used.
The samples are random and independent. A normal sampling distribution
be used because
cannot
can
n1p=enter your response here,
n1q=enter your response here,
n2p=enter your response here,
and
n2q=enter your response here.
(Round to two decimal places as needed.)
State the null and alternative hypotheses, if applicable.
H0:
p1=p2
Ha:
p1≠p2
H0:
p1≤p2
Ha:
p1>p2
H0:
p1≥p2
Ha:
p1<p2
