The manufacturer of a certain toy claims that the mean lead content in this toy is 100 ppm. A sample of 25 such toys produced x = 105.1 ppm. This would provide evidence against the manufacturer's claim if we can show that 105.1 could rarely occur by chance if the claim were true O 105.1 could reasonably occur by chance if the claim were true 100 could reasonably occur by chance if the claim were true 100 could rarely many occur by chance if the claim were true
