A video game company sends out shipments to its various stores with a mean cargo size of 75 games and a standard deviation of 4.8 games. What is the probability a store chosen at random will receive a shipment of between 65 and 85 games?A video game company sends out shipments to its various stores with a mean cargo size of 75 games and...?
z= (x - mu)/sigma
For x=85,
z=(85-75)/4.8 = 2.08333
For x=65,
z=(65-75)/4.8 = -2.08333
By looking up the normal distribution table,
probability for z=2.08333 is 0.4812
Required probability= 0.4812 * 2 = 0.9624
