In a representative sample of 833 coffee growers from Country X, 468 growers were certified to sell to organic coffee markets while 65 growers were transitioning to become organic certified. In Country Y, 67% of coffee growers are organic certified. Is there evidence to indicate that fewer than 67% of the coffee growers in Country X are either organic certified or transitioning to become organic certified? State your conclusion so that there is only a 1% chance of making a Type I error. What are the hypotheses for this test? O A. Ho: p= 0.67 О в. Но: р%3D0.67 Hạ: p#0.67 Hạ: p<0.67 OC.

Calculate the p-value for this test. p-value = (Round to three decimal places as needed.) What is the conclusion of the test? V the null hypothesis because the p-value is the the probability of making a Type I error. Therefore, there is evidence to indicate that fewer than 67% of the coffee growers in Country X are either organic certified or transitioning to become organic certified.
