The 13th day of the month falling on a Friday does not affect hospital admissions from motor vehicle crashes.
The question in the image is about hospital admissions from motor vehicle crashes, but the condition "internal" is not defined. It is possible that "internal" refers to traffic accidents that occur within a hospital or other medical facility. However, this is unlikely, as such accidents would be relatively rare. It is more likely that "internal" is a typo, and that the question is actually about hospital admissions from motor vehicle crashes in general.
If this is the case, then the answer to the question is that the number of hospital admissions from motor vehicle crashes is not affected by whether or not the 13th day of the month falls on a Friday. This is because there is no evidence to suggest that there is a correlation between these two events.
The confidence interval for the mean of the population of differences between hospital admissions on Friday the 6th and Friday the 13th is (-1.78, 3.78). This means that we are 95% confident that the true mean difference between hospital admissions on these two days is somewhere between -1.78 and 3.78. Since this confidence interval includes zero, we cannot reject the claim that there is no difference in hospital admissions between these two days.
In other words, the data does not provide any evidence to suggest that the 13th day of the month falling on a Friday has any effect on the number of hospital admissions from motor vehicle crashes.
Conclusion
The answer to the question in the image is that the number of hospital admissions from motor vehicle crashes is not affected by whether or not the 13th day of the month falls on a Friday. The confidence interval for the mean of the population of differences between hospital admissions on Friday the 6th and Friday the 13th includes zero, so we cannot reject the claim that there is no difference in hospital admissions between these two days.
