A drug is being tested to determine whether it reduces the duration of the symptoms of the common cold, which usually last about 2.5 days with a standard deviation of 0.8 days. If a group of 18 people with the common cold were treated with the new drug and their symptoms alleviated after an average of 2.2 days, the p-value is .056 Is there statistical evidence to suggest that the drug is effective in reducing recovery time at significance level α=0.05 ? a.) No, the p-value is larger than the significance level so we reject H0, which assumes that the drug is effective b.) No, the p-value is larger than the significance level so we fail to reject H0 , which assumes that the drug is ineffective c.) Yes, the p-value is larger than the significance level so we fail to reject H0 , which assumes that the drug is ineffective d.) No, the p-value is larger than the significance level so we reject H0 , which assumes that the drug is ineffective
