An online news Source reports that the proportion of smartphone owners who use a certain operating system is 0.216. Two simulations will be conducte sample proportion from a population with proportion 0.216. Simulation A will consist of 1000 trials with a sample size of S. Simulation will consist of so Which of the following describes the centers and variabilities that should be apparent in the distributions generated by simulation and d bution of the m e The centers will be approximately equal, and the variabilities will roughly be equal on A ) The centers will be approacimately equal, and the variability of simulation B. A will be greater than the variability of simulation C. The centers will be approximately equal and the variety of A belhanth y of The center of simulation A will be greater than the center of simulation and means w e r e D. The center of simulation Aw be less than the center of m otion and the variety of simulation will be less than the way of .

Ответ:
OUR ANSWER IS C
Step-by-step explanation:
Sample distribution is mainly affected by sample size.
As a thumb rule, sampling error reduces by half by increasing sample size four times.
Here, B sample is 2 times the A sample size. So, Center/Mean (which is affected by sampling error) is less for A.
But it's for huge sample. Thus, They are almost same.
Variability of simulation decreases with increase in number of trials. A has less variability.
Thus, Option C is correct.
