A researcher reports that the average income of system analysts in Makati is more than P44,000 per month. A sample of 30 system analysts has mean salary of P45,800 and standard deviation of P5,400. Is there enough evidence to support the claim at a = 0.05? STEP 1: Claim: The average income of system analysts in Makati is [a] P44,000 per month. Ho: The average income of system analysts in Makati is [b] P44,000 per month. Ha: The average income of system analysts in Makati is [c] P44,000 per month. STEP 2: Type of test: [d] Critical value/s: [e] α = 0.05 STEP 3: What is the computed test value? [f] STEP 4: Decision: [g] STEP 5: Conclusion: [h] (Choose the letter of your answer.) A. There is a significant difference between the sample mean and population mean. Thus, there is an enough evidence to support the claim. B. There is no significant difference between the sample mean and population mean. Thus, there is an enough evidence to support the claim. C. There is a significant difference between the sample mean and population mean. Thus, there is no enough evidence to support the claim. D. There is no significant difference between the sample mean and population mean. Thus, there is no enough evidence to support the claim.
