Population Inferences The Mitchell Junior High newspaper staff conducted two samples in which 40 students were randomly selected to represent the entire 600 member student

population. The results of the two surveys are shown below.

Supported

Not Supported

Over 300 students did not support start time after 8:00am

Step-by-step explanation:

Given

--- population

--- sample

See attachment for dataset

Required [True/False]

Over 300  wants start time after 8:00am

First, we calculate the number of samples that wants start time after 8:00am

For sample 1

The corresponding value of x1 in the overall population is:

For sample 2

The corresponding value of x2 in the overall population is:

None of X1 and X2 is greater than 300.

Hence, over 300 students did not support start time after 8:00am

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
