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.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
