Calculate the stability envelope for each of the treatment conditions using the 80/20 formula, in which 80% of the points within the phase are within 20% of the mean. Are the data in both treatment conditions considered stable? (You only need to calculate the last five data points in a condition). This is an A-B-A-B graph. Condition A1 has the following data values - 45, 40, 50, 50, 45. Condition B1 has the following data values - 45, 25, 22, 12, 18, 12. Condition A2 has the following data values - 40, 45, 50, 50. Condition B2 has the follow
