Answer:
854 customers.
Step-by-step explanation:
An online store randomly samples three groups of 100 customers on which delivery method they use. The data shows the results of the three samples.
Overnight 2-day Standard Total
Group (1) 27 20 53 100
Group (2) 32 17 51 100
Group (3) 34 19 47 100
Total customers 93 56 151 300
We have to calculate the number of people who will use overnight delivery.
Out of 300 customer there are 93 people who would use overnight delivery, so the percentage = × 100 = 31%
The online store has 2755 customers one day.
Therefore, 31% of the 2755 customers = × 100 = 854.05 ≈ 854 customers.
854 customers would use overnight delivery.
