Beatriz takes a simple random sample of 350350350 orders from the more than 500050005000 total orders to her store and finds that 12\, percent of the sampled orders were returned. Assuming that it is really 9\%9%9, percent of all orders to her store which were returned, what is the approximate probability that more than 12\, percent of the sampled orders would have been returned

0.02493

Step-by-step explanation:

We are to Find :

P(p > 0.12) ;

This is equivalent to:

1 - P(p ≤ 0.12)

Using the relation :

1 - P((p - po) / (√(po(1 -po)) / n))

1 -P((Z ≤0.12 -0.09) / (√(0.09(1 -0.09)) / 350))

1 -P((Z≤0.03 / (√(0.09(0.91))/350))

1 - P((Z≤0.03 / 0.0152970))

1 - P((Z≤1.96116)

1 - 0.97507 (from Z probability calculator)

= 0.02493

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
