Answer:
A. If 100 pregnant individuals were selected independently from this population, we would expect nothing pregnancies to last less than 184184 days.
Step-by-step explanation:
The mean, standard deviation, and population size can be used for the analysis. In the problem above, the population size is 100 and the estimated number of days for no pregnancy to occur is less than approximately 184 days. This shows that there will not be any pregnancy for any given day that is below the 184th day.
X=16/3 or 5.33333 based on the fact that the angles are congruent
