a) LSD = t * sqrt(MSW *(1/n1 + 1/n2)
df = df within = N-k = 7
t = 2.3646
MSW = 1.222024
for first and second
LSD =2.3646 *sqrt(1.222*(1/4 + 1/3)) = 1.996418
for third
LSD =2.3646 *sqrt(1.222*(1/3 + 1/3))) = 2.13426
b)
difference in means for first = 0.825
for second = 3.6583
for third = 2.8333
if absolute difference > LSD
then difference is significant
hence
second and third pair are significantly different

Some common strategies for treating hypertensive patients by nonpharmacologic methods include (1) weight reduction and (2) trying to get the patient to relax more by meditational or other techniques. These strategies were evaluated by randomizing hypertensive patients to four groups who receive the following types of nonpharmacologic therapy: Group 1: patients receive counselling for both weight reduction and meditation. Group 2: patients receive counselling for weight reduction but not for meditation. Group 3: patients receive counselling for meditation but not...

Problem 3 An experiment was conducted to compare the effectiveness of three new analgesics (painkillers), ?1, ?2, ?3. A clinic evaluated a large group of patients and identified 24 patients with a moderate level of pain. Each of the 24 people was then randomly assigned to one of the three new analgesics. The patients were then placed on therapies and the percentage reduction in pain level was assessed for each patients. Apply the Kruskal-Wallace test to determine if there is...
