Company indicate that at most 45% of employees commute to work using public transportation. You suspect this is incorrect, so you sample 186 random employees and find that 94 of them take public transportation to work. State the null and alternative hypotheses of this test. Null Hypothesis (Ho): Alternative Hypothesis (HA): p P≤ To test our hypothesis, we will assume that p OF 0.4 0 0.4✓ = 0.45 Yes. Both np and n(1 − p) are ≥ 10. No. Either np < 10 or n(1 − p) < 10. Is the success-failure condition of the Central Limit Theorem satisfied? The p-value for this hypothesis test is 0.554 × Report answer accurate to four decimal places. ४
