In number 4 po yung question an "The mean weight for baggage of 25 passengers from USA bound for the Philippines to be checked in an international travel is 31.8 kilos with a standard deviation of 16. Test the claim that the population mean baggage weight is equal to 30 kilos to 0.02 level of significance" Sa statistical decision po niya ay nakalagay an not in the critical region, so we accept null hypothesis and reject the alternative pero bakit po sa conclusion niya ay the test result provide sufficient evidence kung ang statistical decision po ay not in the critical region?
