Using the mean from your sample distribution of 15 means and the standard deviation from the theoretical distribution (i. e. "sigma," the population standard deviation, which is given on the wrksheet) create a 95% confidence interval. Does the confidence interval contain the true mean from the population?

i'm not doing this for the points, i swear. But mn, a picture would be a lot of help

Step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
