Question 1121889: A poll shows that 50% of students play sports. A random sample of 20 students showed that 70% of them play sports.
A number generator was used to simulate 20 samples from a population in which 50% of students play sports. The results are shown in the dot plot.
What is the chance of getting a sample proportion of 70% or greater? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! Need to see the dot plot. Or, count the number of dots 70% or more and divide by 20, the number of samples.
