Answer:
(0.10,0.14)
Step-by-step explanation:
-Given the sample size is 150 and our proportion is 18.
-We first determine the proportion's probability:

-The interval estimate for the proportion is then calculated using the formula:
![CI=\hat p\pm MOE\\\\=0.12\pm 0.02\\\\=[0.10,0.14]](https://tex.z-dn.net/?f=CI%3D%5Chat%20p%5Cpm%20MOE%5C%5C%5C%5C%3D0.12%5Cpm%200.02%5C%5C%5C%5C%3D%5B0.10%2C0.14%5D)
Hence, the interval estimate is for the proportion (0.10,0.14)
Answer:
4 hours
Step-by-step explanation:
55h = 80 + 35h
55h - 35h = 80 + 35h - 35h
20h = 80
20h/20 = 80/20
h = 4
