There is an ongoing debate about whether to label genetically engineered (ge) foods. in the united states, many processed foods include at least one ge ingredient, for example, ge soybeans, corn, or canola. suppose 70% of all americans believe ge foods should be labeled and a random sample of 500 americans is selected. answer part b) using the normal approximation to the binomial distribution. a) is the normal approximation to the binomial appropriate in this situation? do part b) no matter what your answer is. b) find the approximate probability that at least 340 americans believe ge foods should be labeled. remember the continuity correction.

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
