Quiz 3 Ricky is testing soil for a contaminant at a building site. He'll take action to stop construction if there's strong evidence that the soil has more than 400 parts per million (ppm) of the contaminants He plans on using soil from 11, randomly selected locations at the building site. His hypotheses are H0 : p S 400 ppm and HE : [L > 400 ppm, where p is the mean amount of the contaminant in the soil at this site. He's decided to use a signicance level of a = 0.05. Suppose that in reality, H3 is actually true. Which situation below would result in the lowest probability of a Type II error? Choose 1 answer: The true mean is actually 420 ppm, and he uses a sample size of n = 30. The true mean is actually 420 ppm, and he uses a sample size of n = 50. @ The true mean is actually 405 ppm, and he uses a sample size of n = 30. The true mean is actually 405 ppm, and he uses a sample size of n = 50
