H0:p= ; Ha:p not equals≠
What is the test statistic?
z=
(Round to two decimal places as needed.)
Identify the P-value.
The P-value is
What is the correct conclusion for the hypothesis test?
Do not reject H0; the data do not
provide sufficient evidence to conclude that the percentage has changed from
59%.
