Expert Solution
a)
We need to construct the 95% confidence interval for the population proportion. We have been provided with the following information about the number of favorable cases:
| Favorable Cases X = | 4917 |
| Sample Size N = | 10000 |
Therefore, based on the data provided, the 95% confidence interval for the population proportion is 0.482<p<0.501, which indicates that we are 95% confident that the true population proportion p is contained by the interval (0.482, 0.501)
b)
Based on the result, there does not seem to appear to be any indication that people can temporarily postpone their death to survive the holiday as 0.5 lies in the above confidence interval.
