-5x=35
x=35/-5
x=-7
Therefore the equation has only one solution
Answer: A)0.062.
Step-by-step explanation:
Given : The proportion of ales in a population are carriers of a certain infectious disease : ![p_1= 0.25](https://tex.z-dn.net/?f=p_1%3D%200.25)
The proportion of all females in the population are carriers : ![p_2= 0.28](https://tex.z-dn.net/?f=p_2%3D%200.28)
Sample size of men : ![n_1=100](https://tex.z-dn.net/?f=n_1%3D100)
Sample size of women : ![n_2=100](https://tex.z-dn.net/?f=n_2%3D100)
The standard error of the sampling distribution of
is given by :
Substitute all value s, we get
![=\sqrt{0.001875+0.002016}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B0.001875%2B0.002016%7D)
![=\sqrt{0.003891}=0.062377880695\apprrox0.062](https://tex.z-dn.net/?f=%3D%5Csqrt%7B0.003891%7D%3D0.062377880695%5Capprrox0.062)
Hence, the standard deviation of the sampling distribution of
is 0.062.
Thus , the correct answer is A)0.062.
