Answer:
Option C is correct.
The point estimate for the proportion of hotel reservations that are canceled on the intended arrival day from which this interval was constructed = 0.08
Explanation:
Confidence Interval = (Sample Mean) ± (Margin of error)
Upper limit of the confidence interval = (Sample Mean) + (Margin of error)
Lower limit of the confidence interval = (Sample Mean) - (Margin of error)
Let Sample mean = x
Margin of error = y
(0.048, 0.112) = x ± y
x + y = 0.112
x - y = 0.048
Solving this simultaneous equation,
2x = 0.112 + 0.048 = 0.16
x = (0.16/2) = 0.08
y = 0.112 - 0.08 = 0.032
Sample mean = 0.08
Margin of Error = 0.032
So, the point estimate for the proportion of hotel reservations that are canceled on the intended arrival day from which this interval was constructed = 0.08
Hope this Helps!!!
- Let Sample mean = x
- Margin of error = y
- (0.048, 0.112) = x ± y
The branch of science which deals with chemicals and bonds is called chemistry.
The correct answer is 0.08 Â
The formula we will use is as follows:-
[tex]Confidence \ Interval = (Sample \ Mean) + (Margin\ of\ error)[/tex]
The upper limit of the confidence interval = (Sample Mean) + (Margin of error)
The lower limit of the confidence interval = (Sample Mean) - (Margin of error)
All the data is given is as follows:-
- Let Sample mean = x Â
- Margin of error = y Â
- (0.048, 0.112) = x ± y
[tex]x + y = 0.112x - y = 0.048[/tex]
After Solving this equation,
[tex]2x = 0.112 + 0.048 = 0.16 \\\\x = \frac{0.16}{2} = 0.08y = 0.112 - 0.08 = 0.032[/tex]
Hence, the Sample mean is 0.08 Â and Margin of Error is 0.032
So, the point estimate for the proportion of hotel reservations that are canceled on the intended arrival day from which this interval was constructed = 0.08
Hence, the correct answer is 0.08.
