Question

One drive-through car wash facility offers three different types of washes: basic, deluxe, and supreme. The manager of the car wash facility tallies customer selections over three days:

Type of Car Wash: Basic Deluxe Supreme Total
Day Friday: 15 43 19 77
Saturday: 27 52 22 101
Sunday: 23 45 19 87
Total: 65 140 60 265
What proportion of customers selected the deluxe car wash?
Option 1: 0.1698
Option 2: 0.2264
Option 3: 0.5283
Option 4: 0.5584

Answer 1

The proportion of customers selecting the deluxe car wash at the facility is the number of deluxe selections divided by the total selections. With 140 deluxe washes out of 265 total washes, the proportion is approximately 52.83%, making option 3: 0.5283 the correct choice.

Step-by-step explanation:

To find the proportion of customers who selected the deluxe car wash, we first need to look at the total number of customers who chose this option. According to the data provided, a total of 140 customers chose the deluxe option over the three day period. To find the proportion, we divide the number of deluxe car wash selections by the total number of car wash selections. The total number of car washes over the three days is 265.

So, the proportion is calculated as follows:
Proportion of deluxe wash = Number of deluxe selections / Total selections
= 140 / 265
= 0.5283 (when rounded to four decimal places)

Thus, option 3, which is 0.5283, is the correct option in the final answer. This means that approximately 52.83% of the customers selected the deluxe car wash.
