Answer:
n = 116.2 ≈ 117
Option E) 117 is the correct answer.
Step-by-step explanation:
Given the data in the question;
Exceed = 0.1
{ 1 - 0.1 = 0.9 }
normal table value at 0.9 = - 1.285
Normal table;
hence
( y - 400 ) / 40 = -1.285
y - 400 = -51.4
y = 400 - 51.4
y = 348.6
so,
348.6 = ∈(y) = ∈[ ⁿ∑ X ]
348.6 = n.∈( X )
we substitute
348.6 = n × 3
n = 348.6 / 3
n = 116.2 ≈ 117 { roundup since we talking of number of cars i.e sample size }
Option E) 117 is the correct answer.
3 hours . . . 6 minutes . . . 45 seconds
+ 8 hours . . 55 minutes . . . 20 seconds
________________________________
11 hours . . 61 minutes . . . 65 seconds
But 65 seconds = 1 minute . . . 5 seconds
11 hours . . 62 minutes . . . 5 seconds
But 62 minutes = 1 hour . . . 2 minutes
12 hours . . 2 minutes . . . 5 seconds
I think this is regrouping, but with 60s instead of 10s.
