Answer:
a) 0.064
b) 0.109
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 181 centimeter
Standard Deviation, σ = 7.3 centimeter
We are given that the distribution of height for Northern European adult males is a bell shaped distribution that is a normal distribution.
Formula:
a) P(person is between 160 and 170 centimeters)
b) P(person is higher than 190 centimeter)
P(x > 190)
Calculation the value from standard normal z table, we have,

(1) 6 pairs of socks = 1 coat
(2) 2 pairs of jeans = 3 pairs of shoes
(3) 4 pairs of socks = 1 pair of jeans
the last two points are irrelevant becuase we just need socks and coats.
6 pairs of socks are equal to 1 coat.
we need 64 pairs of socks.
so, 64 ÷ 6 = 10.67
so we'll need 10.67 coats for 64 pairs of socks.
i'm not sure if you've typed up the correct numbers becuase i don't think the answer would be expressed as a decimal.
unless we say that we need 11 pairs of coats?
perhaps reread the question again and make sure you've typed it up correctly
xD i hope i've helped.
