In: Statistics and Probability
Create one 90%, one 95%, and one 99.7% confidence interval for the question:
Last night did you get at least 8 hours of sleep?
Yes: 11
No: 48
Total: 59
We have been provided with the following information about the number of favorable cases:
Favorable Cases X = | 11 |
Sample Size N = | 59 |
The sample proportion is computed as follows, based on the sample size N=59 and the number of favorable cases X=11:
a)
We need to construct the 90% confidence interval for the population proportion.
b)
We need to construct the 95% confidence interval for the population proportion.
c)
We need to construct the 99.7% confidence interval for the population proportion.
