5. One study, based on responses from 1,021 randomly selected teenagers, concluded that 42% of teenagers cite grades as their greatest source of pressure. Use a 0.05 significance level to test the claim that fewer than half of all teenagers in the population feel that grades are their greatest source of pressure. See examples in section 9.3 and use normal distribution to find the P-value. State the null and alternative hypotheses. Ho: На: Find the P-value: P-value = Make your conclusion:
