A common idea is that people can temporarily postponed death to survive a major holiday or important event. A study found that there were 6863 deaths before the Thanksgiving and 5930 deaths after the Thanksgiving. Test the claim at the 0.01 significance level that the proportion of deaths in the week before the Thanksgiving is less that 0.5. Based on your result, does it appear that peole can temporarily postpone death to survive the Thanksgiving holiday?

Postponing Death
A common idea is that people can temporarily postponed death to survive a major holiday or important
Given information-
Population proportion, p = 0.5
Sample size, n = 6863 + 5930 = 12793
Significance level, α = 0.01
The sample proportion of deaths in the week before Thanksgiving is-
We have to test the claim that the proportion of deaths in the week before Thanksgiving is less than 0.5.
