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:
500g Jelly beans $9.90
Step-by-step explanation:
To know the values.
Let's know how much a gram will cost in each case
300g Jelly beans $5.80
1g = 5.8/300
1 g = 0.01933
500g Jelly beans $9.90
1g = 9.9/500
1g =0.0198
It's obvious that the second one has more value placed on it as it cost more per gram
