In a study of the effect of a new drug on the alleviation of asthma symptoms, the σM for symptom relief in the patient group that received the new drug is 1.45, and the σM for symptom relief in the group that did not receive the new drug is 1.22. Calculate the σM1-M2.

σM = σ/sqrt(n)

σM1-M2=sqrt((σM1)^2+(σM2)^2)

σM1-M2=sqrt(1.45^2+1.22^2)

σM1-M2= sqrt(3.5909)

σM1-M2= 1.895
