Answer: Given a sample of 200, we are 90% confident that the true proportion of people who watched educational TV is between 72.1% and 81.9%.
Step-by-step explanation:
![\frac{154}{200} =0.77](https://tex.z-dn.net/?f=%5Cfrac%7B154%7D%7B200%7D%20%3D0.77)
![1-0.77=0.23](https://tex.z-dn.net/?f=1-0.77%3D0.23)
=0.049
0.77±0.049< 0.819, 0.721
Answer:
m=-44
Explanation: distribute the negative and add -1/4 to m and then take the 5 away from 16 and then multiply both sides
5x-3=42. To solve you add three to both sides making the equation 5x=45. Then you divide both sides by five, and you get 9 as your answer.
