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.
1/4 x 16
= 16 ÷ 4
= 4
1/3 x 24
= 24 ÷ 3
= 8
8 is greater than 4, so one third of 24 is bigger than one fourth of 16

Your answer is b because 8 more(+) than 2 a number(n) is(=) 50
