Question

A private school official claims that more than 80% of the students who come to their school to prepare for the university entrance exam, get the degree they want at the university. In order to investigate this claim, 120 randomly selected students from among the students who went to the said school and won the university were asked whether they won the department they wanted or not, and it was learned that 102 students won the department they wanted in the university. Make a hypothesis about the claim of the official and decide. Which option is correct? H0 : P ≤ 0.80 H1 : P > 0.80; Decision: The Ho hypothesis cannot be rejected. H0 : P ≤ 0.85 H1 : P > 0.85; Decision: Ho hypothesis is rejected. H0 : P = 0.80 H1 : P < 0.80; Decision: Ho hypothesis is rejected. H0 : P = 0.85 H1 : P ≠ 0.85; Decision: The Ho hypothesis cannot be rejected. H0 : P = 0.80 H1 : P ≠ 0.80; Decision: Ho hypothesis is rejected.
