An accounts receivable auditor is examining accounts for a client. The accounts receivable balance can be considered as a continuous random variable that exhibits normal distribution characteristics. The mean amount due per account is $5000. The standard deviation from the mean is $1000. The auditor selects an account at random.
The probability that the account selected by the Auditor has a balance which is outside of the range between $6500 and $7000 is:
A. .05B. .10C. 1.20D. .96E. .00
