Answer:
0.025 is the standard error of mean.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 100
Sample mean = 13 psi
Population standard deviation = 0.25 psi
We have to find the standard error of the mean.
Formula:
Standard error =
0.025 is the standard error of mean.
Three and six tenths

To find the slope take two ordered pairs and put them in form of x2-x1/y2-y1 and then you can find the slope.
(-2,17) (-3,20)
(-2)-(-3) = 1
(17)-(20)=-3
slope is 1/-3
12 - t|3r - 2|
r = -6; t = 3
subtitute:
12 - 3 · |3 · (-6) - 2| = 12 - 3 · |-18 - 2| = 12 - 3 · |-20| = 12 - 3 · 20 = 12 - 60 = -48
