Step-by-step explanation:
Answer:
0.9544
Step-by-step explanation:
P(-2 < Z < 2) means that Z has mean 0 and standard deviation 2.
P(−2 < Z < 2) = F(2) - F(-2)
Using the Z - table,
F(2) = 0.9772
and F(-2) = 0.0228
Thus,
P(−2 < Z < 2) = 0.9772 - 0.0228 = 0.9544
This means that data within two standard deviation is 95%.
Answer:
y=11/4x-13/4
Step-by-step explanation:
Use the slope formula and slope-intercept form y=mx+b to find the equation.
Pretty good so far its hard also.
