B . 2 and 9... Brainleist please
Answer:
Step-by-step explanation:
Let X be the mean lifespan of automobile tire
X is N(36,000, 2450)
The Z scores are calculated as (x-36000)/2450
x x-36000 Z=(x-36000)/2450
34000 -2000 -0.816326531 =-0.82
38000 2000 0.816326531 =0.82
31000 -5000 -2.040816327 =-2.04
No only if beyond |3| z score is there we say unusual
For 33550 miles
Z = -1
P(Z<-1) = 0.3413
So percentile is 34.13
For 36000 , z=0 so 50th percentile
Answer:
32 cm
