A local bank has determined that the daily balances of the checking accounts of its customers are normally distributed with an average of $280 and a standard deviation of $20. What percentage of its customers' balances is between $241 and $301.60?

83.43% of customer's balances is between $241 and $301.60.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = $280

Standard Deviation, σ = $20

We are given that the distribution of daily balance is a bell shaped distribution that is a normal distribution.

Formula:

P(customer's balances is between $241 and $301.60)

Thus, 83.43% of customer's balances is between $241 and $301.60.
