2. Average Senior High School annual cost of tuition fee for all private schools last year
was Php43,700. A random sample of costs this year for 45 private schools indicated
that the sample mean was Php45,800 and a sample standard deviation was Php5,600.
At 0.01 level of significance, is there sufficient evidence to conclude that the cost
increased?
