Answer:
p = 0.68 and p^ = 0.6
Step-by-step explanation:
Jackie received 68% of the votes in an election.
Here p is the decimal equivalent of 68 %.Hence ,
p = 0.68
Now we have taken a sample of 30 people from the total number of voters and we have to find the percentage of votes that Jackie gets in this .
Out of 30 people Jackie got 18 votes. Hence,
p^ = = 0.6
Hence the values are
p = 0.68 and p^ = 0.6
In the random sample we have taken the probability of Jackie has decreased but it will be compensated by another sample where it will be more.
