In a fruit tree farm, samples were collected to be examined for pesticide residues. The committee selected a sample of 45 boxes from a total of 500 boxes. It was found that the average rate of pesticide residues was 28 ppm with a standard deviation of 10 ppm, while the percentage of pesticides should not exceed 25 ppm. Is the shipment accepted for export or not at the level of significance of 5%?
