In 2010, shortly before a country's midterm elections, people in that country were dissatisfied with government and 55% of adults in the country thought that a third major party was needed. In a
recent poll, 59% of 1162 adults in the country felt the same way. At the 2% significance level, do the data provide sufficient evidence to conclude that the percentage of all adults in the country
who now think that a third major party is needed has changed from that in 2010? Use the one-proportion z-test to perform the appropriate hypothesis test.
.....
What are the hypotheses for the one-proportion z-test?
; Ha: p
Ho: p=
(Type integers or decimals.)
What is the test statistic?
(Round to two decimal places as needed.)
Identify the P-value.
The P-value is
(Round to three decimal places as needed.)
