Answer:
c. We are 95% confident that the average taxi fare between Logan Airport and downtown Boston will fall between $20.51 and $24.21.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
95% confidence interval of [$20.52, $22.48].
We can be 95% sure that the true mean amount of taxis fares in downtown Boston is in this interval, and thus, the correct answer is given by option C.
Answer:
Net Cash-flow = Cash Inflows - Cash Outflows
The net amount of cash that a company has is the difference between the cash coming in(revenue) and the cash going out (expenses).
Spreadsheet 1
= Cash Inflows - Cashflows
= 2,350 - 2,335
= $15
Spreadsheet 2
= Cash Inflows - Cashflows
= 2,270 - 2,260
= $10
Spreadsheet 3
= Cash Inflows - Cashflows
= 2,380 - 2,380
= $0
Spreadsheet 4
= Cash Inflows - Cashflows
= 2,150 - 2,055
= $95
Spreadsheet 4 has the greatest net cash flow at $95.
