Determine the null and alternative hypothesis. “It was claimed that the average monthly income of aircraft pilot was ₱116, 714.00. A random sample of 45 pilots is selected and it is found out that the average monthly salary is ₱ 120,000. Using a 0.01 level of significance, can it be concluded that there is an increase in the average monthly income of pilot?”
𝐻𝑜: μ=₱116,714.00,𝐻𝑎: μ≤₱116,714.00
𝐻𝑜: μ=₱116,714.00,𝐻𝑎: μ≠₱116,714.00
𝐻𝑜: μ=₱116,714.00,𝐻𝑎: μ>₱116,714.00
𝐻𝑜: μ=₱116,714.00,𝐻𝑎: μ<₱116,714.00
