They cancel out so the final answer is just "b"
Answer: lower bound = 0.7404; upper bound = 0.8596
Step-by-step explanation:
The proportion p for this population:
p =
p = 0.8
Confidence interval for proportion is calculated as:
p ± z-score.
Z-score for a 99% confidence interval is: z = 2.58
Calculating:
0.8 ± 2.58.
0.8 ± 2.58.
0.8 ± 2.58(0.0231)
0.8 ± 0.0596
This means that the lower limit of this interval is 0.7404 and upper bound is 0.8596
Well, you wrote a list of 10 numbers, and
you called the list "Their answers".
If their answers are written as a list of 10 numbers,
and if there's no hanky panky going on that you're
not telling us, then the 10 answers came from
asking 10 students.
