At Community Hospital, the burn center is experimenting with a new plasma compress treatment. A random sample of n, = 336 patients with minor burns received the plasma compress treatment. Of these patients, it was found that 254 had no visible scars after treatment. Another random sample of n, = 400 patients with minor burns received no plasma compress treatment. For this group, it was found that 103 had no visible scars after treatment. Let p, be the population proportion of all patients with minor burns receiving the plasma compress treatment who have no visible scars. Let p, be the population proportion of all patients with minor burns not receiving the plasma compress treatment who have no visible scars.

Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
