I believe it would just be 28.28
men are my favourite type of gender. They satisfy me so much, thank god.
Answer: the probability that fewer than 100 in a random sample of 818 men are bald is 0.9830
Step-by-step explanation:
Given that;
p = 10% = 0.1
so let q = 1 - p = 1 - 0.1 = 0.9
n = 818
μ = np = 818 × 0.1 = 81.8
α = √(npq) = √( 818 × 0.1 × 0.9 ) = √73.62 = 8.58
Now to find P( x < 100)
we say;
Z = (X-μ / α) = ((100-81.8) / 8.58) = 18.2 / 8.58 = 2.12
P(x<100) = P(z < 2.12)
from z-score table
P(z < 2.12) = 0.9830
Therefore the probability that fewer than 100 in a random sample of 818 men are bald is 0.9830
For this case we have the following possible cases:
Case 1:
If the scale factor meets 0 <k <1 then the original figure shows a reduction.
Case 1:
If the scale factor complies with k> 1 then, the original figure presents an expansion.
In this case, the scale factor is:
k = 2 (k> 1)
Therefore, the figure presents an expansion.
