Many people think that a national lobby's successful fight against gun control legislation is reflecting the will of a minority of americans. a random sample of 4000 citizens yielded 2250 who are in favor of gun control legislation. compute the point estimate for the proportion of citizens who are in favor of gun control legislation. round to four decimal places.

Step-by-step explanation:

Given : Sample size :

The number of people who are in favor of gun control legislation =2250

The proportion of people who are in favor of gun control legislation will be :-

We assume that the the given situation is normally distributed.

Then , the point estimate for the proportion of citizens who are in favor of gun control legislation is equals to the sample proportion.

i.e.  

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
