Two researchers conduct separate studies to test Ho: p=0.50
against Ha: p0.50, each with n = 400. Researcher A gets 226
observations in the category of interest, and
p=
6=226/400=0.565. Researcher B gets 225 in the category of
interest, and p = 225/400=0.5625. Complete parts (a) through
(d) below.
a. Find the z-scores and P-values for both researchers.

Z =
Researcher B
Z =
P-value =
P-value =
(Round the z-scores to two decimal places as needed. Round
the P-values to three decimal places as needed.)
The result in case A is
The result in case B is
b. Using α = 0.01, indicate in each case whether the result is
"statistically significant." Interpret.
What does the statistical significance of the results above imply?
OA. A difference in conclusions between two hypothesis
tests does not necessarily mean that the test with the
result that is deemed "statistically significant" is actually
much more significant than the test with the result that
is deemed "not statistically…
Recall the data for the three populations.
