A random sample of 25 students at a certain high school was asked if they sleep at least 7 hours per night. Assume the true proportion of students that sleep at least 7
hours per night is 45%. Which of the following is closest to the probability that fewer
than 40% of the students in a sample would respond that they spend at least 7 hours
per night sleeping?

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

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. : )
