Question
Suppose media reports that no more than 34% of doctors recommend wearing face masks. You suspect this is incorrect, so you sample 120 random doctors and find that 51 of them recommend wearing face masks. State the null and alternative hypotheses of this test. Null Hypothesis (Ho): Alternative Hypothesis (HA): p р To test our hypothesis, we will assume that p = .34✓ .34✓✔ O Is the success-failure condition of the Central Limit Theorem satisfied? O No. Either np < 10 or n(1 − p) < 10. Yes. Both np and n(1 − p) are ≥ 10. The p-value for this hypothesis test is Report answer accurate to four decimal places. Then, according to the Central Limit Theorem, the distribution of sample proportions is approximately normal with mean and standard deviation
