On a standardized science test, the seniors at Fillmore High School have a mean score of 430 with a standard deviation of 90.

For random samples of 100 seniors, what interval centered on the mean of the sampling distribution captures 68% of the mean scores? If necessary, round to the nearest tenth. Enter the interval from least to greatest.

For random samples of 100 seniors, 68% of the sample means fall between and ___

For random samples of 100 seniors, 68% of the sample means fall between 340 and 520

Step-by-step explanation:

As a property of normal distribution, 68% of sample means fall between mean - sigma(430 - 90 = 340) and mean + sigma (430 + 90 = 520) (here, sigma is standard deviation).

Hope this helps!

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)
