Answer: D) We are 95% confident that the average taxi fare between Logan Airport and downtown Boston will fall between $20.51 and $24.21.

Explanation:

The Confidence interval allows one to speculate between which values the average of a population will be. In a 95% confidence interval, this means that we are 95% certain that the average value of a variable will be between the higher and lower limits set by the interval.

The 95% confidence interval here has an upper limit of  $24.2091 and a lower limit of $20.5051 for taxi fares from Logan Airport to downtown Boston. This means that with a 95% certainty, the taxi charge from Logan Airport to downtown Boston will be between these 2 charges so you can expect to pay an amount between them.

The firm receives an average of $20,000 in checks per day. The weighted average delay in clearing the checks received is 3 days.
katrin [286]

Answer:

<u>$26000</u>

Explanation:

from the question;

check per day; 20000

delay: 3 days

checks to pay suppliers; 17000

clearing time 2 days

<u>we first calculate collection flaot:</u>

collection flaot = average amount of check x outstanding days

= 20000 x 3

= 60000

now we have to calculate <u>disbursements float:</u>

average amount of check x days to clear

= 17000 x 2

= 34000

with these two values we can get the net float

= collection flaot - disbursements float

= 60000 - 34000

= <u>$26000</u>

alexandr402 [8]

The new ordinance will make a difference when the new wages will be binding.

<h3>How to depict the information?</h3>

It should be noted that the supply curve shows the relationship between the price and the quantity supplied.

Based on the information given, when the equilibrium wage is above the minimum wage, the ordinance won't make a difference.

On the other hand, when the equilibrium wage is below the minimum wage, it'll make a difference for the worker.

Therefore, joining the lowest of the two points will give the equilibrium.
