Question

bank survey
a regional bank is analyzing its customer base to improve its services and
offerings.
the bank categorizes its customers based on their preferred banking
method (online vs. in person) and their primary account type (checking vs.
savings). here is the collected data for a sample of 600 customers:

• 300 customers prefer online banking, with 180 primarily using a

checking account.

• the total number of customers who prefer in - person banking and

primarily use a savings account is 150.
the bank is interested in understanding the distribution and preferences of
its customers to tailor its marketing strategies more effectively.
construct the relative frequency table on the given data. how many
customers prefer in - person banking and primarily use a checking account?
250
100
150
200

Explanation:

Step1: Calculate online savings account customers

Total online customers = 300, online checking = 180. So online savings = \(300 - 180=120\)

Step2: Calculate in - person checking account customers

Total checking + savings = 600. Total savings = online savings+in - person savings=\(120 + 150 = 270\). So total checking=\(600 - 270 = 330\). In - person checking=\(330 - 180=150\)

Answer:

150
