A bank's customer complaints are: billing errors=45, account access=30, transaction disputes=60, other=15. What percentage are transaction disputes?
Answer: 40%
Total complaints = 150; transaction disputes = 60; 60/150 × 100 = 40%.
Q1 sales data: January $85,000, February $92,000, March $78,000. What is the range of the data?
Answer: $14,000
Range = highest value − lowest value = $92,000 − $78,000 = $14,000.
A scatter plot shows a strong positive correlation between customer income and credit limit. What does this mean?
Answer: Higher income customers tend to have higher credit limits
A positive correlation means that as one variable (income) increases, the other variable (credit limit) also tends to increase.
A bank's loan default rates over five quarters are: 2.3%, 2.1%, 3.4%, 1.9%, 2.8%. What is the mean default rate?
Answer: 2.5%
Mean = (2.3+2.1+3.4+1.9+2.8)/5 = 12.5/5 = 2.5%.
Customer satisfaction scores increased 15% year-over-year. If last year's score was 72, what is the current score?
Answer: 82.8
Current score = 72 × 1.15 = 82.8.
Transaction volumes: savings accounts=1,000, checking accounts=2,000, credit cards=4,000, loans=1,000. What fraction of total transactions are credit card transactions?
Answer: 1/2
Total transactions = 8,000; credit card transactions = 4,000; 4,000/8,000 = 1/2.
Monthly new account openings averaged 450 in Q1 and 520 in Q2. By what percentage did the monthly average increase from Q1 to Q2?
Answer: 15.6%
