A project manager is trying to project net profit a new product to launch next year. The model include cost for labor, cost of parts, demand for the product, selling price per unit and fixed costs. Demand is measured by the number of units to be sold and is uncertain input. Based on historical data for a similar product shows that number of units is random variable normally distributed with a mean of $80,000$ and standard deviation of $10,000$ units. The manager should simulate the number of units with the following formula:

Group of answer choices

$=$NORM.INV$($RAND$(),80,000,10000)$

$=$NORM.INV$($RAND$(),60000,15000)$

$=(80000+(60000-10000)*$RAND$())$

$=$Rand$()$
