9. Mang Kiko, a banana plantation owner, plans to expand his banana business due to recent calamities that happened in their area. From an average of 15 million tons of banana produced per year in his plantation, the number has decreased to only 4 million tons. He plans to expand his business to Davao, where most of the banana plantations can be found, if the average banana production will exceed the recent banana production in his plantation. Hence, he took a random sample of 25 barangays in Davao and found a mean of 4.3 million tons. The appropriate null and alternative hypotheses test if Mang Kiko will expand his business are O A. Ho: u=4 vs. Ha: u>4 O A. Ho: u=4.3 vs. Ha: u>4.3 O C. Ho: X=4 vs. Ha: X>4 O C. Ho: X=4.3 vs. Ha: X>4.3
