A team from the Department of Trade and Industry (DTI) suspects that a local supermarket's 25 kilograms of commercial rice actually weighs less than 25 kilograms. The team took a random sample of 15 sacks of commercial rice, weigh each sack and found the average sample to be 24.75 kilograms with a standard deviation of 1.25 kilograms. Using 5% significance level, would the team from DTI conclude that the average weight is less than 25 kilograms
