Given : The owner of the West End Kwick Fill Gas Station wishes to determine the proportion of customers who pay at the pump using a credit card or debit card.
He surveys 100 customers and finds that 80 paid at the pump.
Then, sample proportion=
Since , the best point estimate for population proportion is sample proportion.
Therefore, the estimated value for population proportion =0.80
The answer is 6$ because 50% of 40 would be 20 and 50% of 20 is 10 but when you all on the tax which would be around a dollar when you take 50% of 10 which is 5 and add on the tax which is a dollar you then get 6$ in total.
