blem 2 A genetic model suggests that 80 of plants grown from a cross between two given strains of seeds will be of the dwarf variety After breeding a sample of these plants 154 were observed to be of the dwarf variety Suppose that we do a hypothesis test to see if the sample results strongly contradict the genetic model and find the p value to be 0 0154 What is the meaning of this p value A The p value of 0 0154 is the probability of making a wrong decision B The p value of 0 0154 is the probability of making a Type II error C If the genetic model is not correct it is very unlikely probability 0 0154 to obtain 154 or more plants of the dwarf variety in the given sample D The p value of 0 0154 is the probability of making a Type I error E If the genetic model is correct it is very unlikely probability 0 0154 to obtain exactly 154 plants of the dwarf variety in the given sample F If the genetic model is correct it is very unlikely probability 0 0154 to obtain 154 or more plants of the dwarf variety in the given sample G If the genetic model is not correct it is very unlikely probability 0 0154 to obtain exactly 154 plants of the dwarf variety in the given sample
