A random sample of 50 bottles is selected from the production line of a large manufacturing company. The mean weight of the contents of the 50 bottles is 20.25 ounces. The manager of the company requests that the machines be recalibrated because bottles coming off the production line are supposed to contain 20 ounces. Which of the following statements is true? The population is the production line that needs to be recalibrated and the sample is all production lines.

The population is all production lines and the sample is the production line that needs to be recalibrated.

The population is all bottles in the production line and the sample is the 50 bottles that were selected.

The population is the 50 bottles that were selected and the population is all bottles in the production line.

The population is all bottles in the production line and the sample is the 50 bottles that were selected.

P.S. im on unit 7 test i believe you are still in unit 6 I can help you *wink wink with the assignments and quizs

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
