Mr. Jones wants to study voting patterns. He Calculated that, on average, 60% of adults vote. He obtained a random sample of 20 adults. Answer the following:

3. If Mr. Jones picked another sample of 20 adults, using table 2, waht is the probability of having 10 or more voters?

4. What would be the probability of having 5 or fewer voters?

5.What is the expected number of voters one would have in a sample of 20?

6.How does Mr. Jones’ earlier sample data compare to this expected number?

7. Could one expect to get at least 10 voters in a sample of 20? Why or why not?

 

I need help with this before 2pm EST.
