At Community Hospital, the burn center is experimenting with a new plasma compress treatment. A random sample of n₁ = 403 patients with minor burns received the plasma compress treatment. Of these patients, it was found that 306 had no visible scars after treatment. Another random sample of n₂ = 606 patients with minor burns received no plasma compress treatment. For this group, it was found that 567 had no visible scars after treatment. Let p₁ be the population proportion of all patients with minor burns receiving the plasma compress 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 99% confidence interval for P₁ P2. (Use 4 decimal places.) Lower Limit Upper Limit (b) Choose the correct conclusion Owe can not say that there is a higher proportion of patients with no visible scars among those who received the treatment. O we can say with 99% confidence that there is a higher proportion of patients with no visible scars among those who did not receive the treatment. Owe can say with 99% confidence that there is a higher proportion of patients with no visible scars among those who received the treatment.

Question
Transcribed Image Text:At Community Hospital, the burn center is experimenting with a new plasma compress
treatment. A random sample of n₁ = 403 patients with minor burns received the plasma compress
treatment. Of these patients, it was found that 306 had no visible scars after treatment. Another
random sample of n₂ = 606 patients with minor burns received no plasma compress treatment.
For this group, it was found that 567 had no visible scars after treatment. Let p₁ be the
population proportion of all patients with minor burns receiving the plasma compress 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 99% confidence interval for P₁ P2. (Use 4 decimal places.)

(b) Choose the correct conclusion
Owe can not say that there is a higher proportion of patients with no visible scars among those who
received the treatment.
O we can say with 99% confidence that there is a higher proportion of patients with no visible scars
among those who did not receive the treatment.
Owe can say with 99% confidence that there is a higher proportion of patients with no visible scars
among those who received the treatment.
