use technology or a z-score table to answer the question.

the average balance at a credit union is normally distributed with a mean of $240 and a standard deviation of $100. joe's balance is $260.

what percent of all accounts at the credit union have a balance less than joe's?

round your answer to the nearest whole number.

 b) 58%

Step-by-step explanation:

First, let's find the z-score using the formula:

Next, refer to the z-score table below to find the value of 0.20

Look on the left side for 0.20 and the top for 0.00 to find the percent for 0.20.  The table shows the percent above the MEAN so you need to add the percent below the mean (50%) to the value in the table.

  0.0793

+ 0.5      

  0.5793    = 57.93%
