Question

the two-way table below describes the car rental habits of sales representatives attending a conference.

sales representatives car rentals, by length of stay

	staying fewer than two nights	staying at least two nights
did not rent a car	21	14

what percentage of representatives staying at least two nights rented a car?

• 20%
• 44%
• 55%
• 79%

Explanation:

Identify the target group and condition

$$ \text{Condition: Staying at least two nights} $$

Calculate the total for the target group

$$ \text{Total} = 11 \text{ (Rented)} + 14 \text{ (Did Not Rent)} = 25 $$

Calculate the conditional percentage

$$ \text{Percentage} = \frac{11}{25} \times 100\% = 44\% $$

Answer:

• 20%
• 44% (Correct answer)
• 55%
• 79%
