Problem#1
Show: Step 1: State the hypothesis Step 2: The level of significance, degree of freedom and critical region Step 3: Compute for the value Step 4: Decision rule Step 5: Conclusion 1. A survey of the National Capital Region finds the average commute time of employees on one way is 45 minutes. The Makati Chamber of Commerce feels that in their city it is greater and want to publicize this. They randomly selected 28 commuters and found the average is 50 minutes with a standard deviation of 6 minutes. At 0.05 level of significance. 2. The average pre-school cost for tuition fees last year was P17,250. The following year, 20 institutions had a mean of P16,150 and a standard deviation of P2,250. Is there sufficient evidence at 0.10 level of significance to conclude that the mean cost has increased?
