The y-value changes from 10 to 70 as the x-value changes from 0 to 10. That makes the slope (70 -10)/(10 -0) = 6, and the y-intercept = 10.
Selection A is the appropriate equation.
Answer:
it should be the negative repirocal of -2 so 1/2
Answer:
The claimed proportion (population) is
![p=0.11](https://tex.z-dn.net/?f=p%3D0.11)
The sample proportion (p-hat) is
![\hat{p}=0.10](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%3D0.10)
Step-by-step explanation:
In the population, we have the parameter p that is 11%.
![p=0.11](https://tex.z-dn.net/?f=p%3D0.11)
Then, a sample of n=160 is taken and the proportion of the sample is 0.10.
![\hat{p}=0.10](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%3D0.10)
The sample proportion p-hat can differ from the population's proportion. There is a sampling distribution that gives the possible values of the sample proportion taken out of this population and its associated probabilities.
