Answer:
Supplemental agreement
Explanation:
A supplemental agreement is an agreement which is modified (but not replaced and/or rearranged) with the mutual understanding and consent of both the parties involved. The binding spirit of the contract is not affected because of this modification, nor the mutual considerations to be transferred. The reason behind a supplemental agreement could be anything, it might be because for the inclusion of some important consequences that were previously left unmentioned, which could have increased the contractual inadequacy risk for both the parties or any reason detrimental to legal and/or financial capacity of the parties involved.
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.
