At
community Hospital the burn center experimenting with a new plasma
compress treatment. A random sample of n1= 330 patients with minor
burns received the plasma compress treatment. Of these patients, it
was found that 258 had no visible scars after treatment. After
random sample of n2= 436 patients with minor burns received no
plasma compress treatment. For this group, it was found that 87 had
no visible scars after treatment. Let p1 be the population
proportion of all patients with minor burns receiving the plasma
compressed treatment who have no visible scars. Let p2 be the
population proportion of all patients with minor burns not
receiving the plasma compress treatment who have no visible scars.
(a) Find a 95% confidence interval for p1- p2
