Answer:
0.005 `; 0.00499 ;
No, because np < 10 ;
2000
Step-by-step explanation:
Given that:
Number of samples , n = 100
Proportion, p = x / n
p = 1 / 200
= 0.005
p = μ
Standard deviation of sample proportion :
σp = sqrt((p(1 - p)) / n)
σp = sqrt((0.005(1 - 0.005)) / 200)
σp = sqrt((0.005(0.995)) / 200)
σp = sqrt(0.004975 / 200)
σp = sqrt(0.000024875)
σp = 0.0049874
σp = 0.00499
np = 100 * 0.005 = 0.5
n(1 - p) = 100(1-0.05) = 95
Smallest value of n for which sampling distribution is approximately normal
np ≥ 10
0.005n ≥ 10
To obtain the smallest value of n,
0.005n = 10
n = 10 / 0.005
n = 2000
Answer:
(2,1/4)
Step-by-step explanation:
y=(1/2)^x
we should substitute (x,y) in all points.
From this!
y=1/4,x=2
Then,
1/4=(1/2)^2
1/4=(1^2/2^2)
therefore 1/4=1/4
Answer:
Step-by-step explanation:
<u>Volume of a cone:</u>
<u>We have:</u>
- V = 1200 cm³
- r = 6 cm
- h = ?
<u>Substitute values and solve for h:</u>
- 1200 = 1/3*3.14*6²h
- 1200 = 37.68h
- h = 1200/37.68
- h = 31.8 cm (rounded)
None of the choices is correct
Answer:
m+p/2=n
Step-by-step explanation:
You can't get any other multiplication factor, so the only way is to isolate n, by adding p to m and dividing by 2
