Question
A research center claims that more than 30% of employees in a certain country have changed jobs in the past three years. In a random sample of 360 people from that country, 126 have changed jobs in the past three years. At a = 0.05, is there enough evidence to
support the center's claim? Complete parts (a) through (e) below.
(a) Identify the claim and state Ho and Ha.
