A student researcher claims that fewer than 8% of the Junior High School completers will enroll in private Senior High Schools. To test this claim, he collected sufficient samples randomly and found out that 85 out of 380 Junior High School completers are planning to enroll in private Senior High Schools. Give the Null hypothesis (with mathematical model): Alternative hypothesis (with mathematical model):
