What is the probability that a value falls in the interval μ ± 2σ, that computes the probability p(-2 < z < 2). round to four decimals and use leading zeros

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%.

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
