Aprincipal believes 50% of her music students reported their practice hours accurately. based on that assumption, she ran 200 simulations of random samples. she found the mean of each run. then she found the mean, 48%, and standard deviation of all the means, 18%, to create a normal distribution. according to that distribution, which option below gives the best description of how likely is it that a single survey would return a mean of 30%?

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.

kaahe btau

school a:

minimum value is 2

maximum value is 22

the lower quartile is 2.5

the median is 10

the upper quartile is 15.5

school b:

minimum value is 9

maximum value is 20

the lower quartile is 12

the median is 16

the upper quartile is 18

box plot for school a isn't symmetrical. the data tails on the right

box plot for school b isn't symmetrical. the data tails on the left

hope i
