5. A new drug to treat psoriasis has been developed and is in clinical testing. Assume that those individuals given the drug are examined before receiving the treatment and then again after receiving the treatment to determine if there was a change in their symptom status. If the initial results showed that 3.0% of individuals entered the study in remission: T4055 of individuals entered the study with mild symptoms, 13.0% of individuals entered the study with moderate symptoms, and 4.0% entered the study with severe symptoms calculate and interpret a chisquared test to determine if the drug was effective treating psoriasis given the information below from the nal examination. Total Number of Participants to Receive the Drug Remission {No Mild Moderate Severe Symptoms of Symptoms of Symptoms of Symptoms of Psoriasis) Psoriasis Psoriasis Psoriasis 455 635 85 7' 1 182 A] We reject H0 because 5094.4 is greater than 5.09. We have statistically signicant evidence at the alpha equals .05 level to show that the distribution of the severity of psoriasis cases at the end of the clinical trial for the sample is different from the distribution of the severity of psoriasis cases prior to the administration of the drug, suggesting the drug is effective. B) We reject H0 because 50944 is greater than 9.51. We have statistically signicant evidence at the alpha equals .05 level to show that the distribution of the severity of psoriasis cases at the end of the clinical trial for the sample is different from the distribution of the severity of psoriasis cases prior to the administration of the drug, suggesting the drug is effective. C} We reject H0 because 5094.4 is greater than 181. We have statistically signicant evidence at the alpha equals .05 level to show that the distribution of the severity of psoriasis cases at the end of the clinical trial for the sample is different from the distribution of the severity of psoriasis cases prior to the administration of the drug, suggesting the dmg is effective. D} We reject H0 because 5094.4 is greater than 11.0? We have statistically signicant evidence at the alpha equals .05 level to show that the distribution of the severity of psoriasis cases at the end of the clinical trial for the sample is different from the distribution of the severity of psoriasis cases prior to the administration of the drug, suggesting the drug is effective
