Explanation:
The answer is D. Neither A or B
Answer:
n = 100 customers
X = 80 who paid at the pump
A) the sample proportion = p = X / n = 80 / 100 = 0.8
we can definitely state that 80% of the customers paid at the pump.
B) if we want to determine the 95% confidence interval:
z (95%) = 1.96
confidence interval = p +/- z x √{[p(1 - p)] / n}
0.80 +/- 1.96 x √{[0.8(1 - 0.8)] / 100}
0.80 +/- 1.96 x √{(0.8 x 0.2) / 100}
0.80 +/- 1.96 x √{(0.8 x 0.2) / 100}
0.80 +/- 1.96 x 0.4
0.80 +/- 0.0784
confidence interval = (0.7216 ; 0.8784)
C) We can estimate with a 95% confidence that between 72.16% and 87.84% of the customers pay at the pump.
