Answer:
16%
Step-by-step explanation:
Calculate the z score.
z = (x − μ) / σ
z = (2.5 − 3.1) / 0.6
z = -1
According to empirical rule, 68% is between -1 and +1 standard deviations.
P(-1 < Z < 1) = 68%
Since normal distributions are symmetrical, 34% is between -1 and 0 standard deviations.
P(-1 < Z < 0) = 68% / 2 = 34%
And since 50% is less than 0 standard deviations, that means 16% is less than -1 standard deviations.
P(Z < -1) = 50% − 34% = 16%
Answer:
8 (miles per hour)
Step-by-step explanation:
do 112/ 14 and divide 112 by 4
when you do that your answer is 8 so 8 (lets use miles per hour because you didn't give a specific unit) miles per hour
I really hope this helped!
