A major television manufacturer has determined that its 40-inch LED televisions have a meanservice life that can be modeled by a normal distribution with a mean of six years and a standarddeviation of one-half year.a. What probability can you assign to service lives of at least (1) five years? (2) six years? (3)seven and one-half years?
The warehouse management system (WMS) of RoyaTech's
Delaware Valley warehouse tracks service level at the
warehouse. A service level failure at the warehouse is an event
where a customer's order could not be shipped out in full by
the promised shipping time.
RoyalTech's ordering system prevents customers from placing
orders on products that are not in-stock at the warehouse.
Therefore, we can make the statement that "the WMS is
guaranteed to show 100% service level at the warehouse."
Choose the most appropriate statement in response:
O True, because orders will be placed only for products that are
available.
O False, because service level can never be 100%.
O False, because resource constraint or human error may delay the
shipping even though inventory is available in the system.
O False, because WMS calculations are faulty.
You are a food specialist in a company that specializes inrefrigerated delicacies, and one of your brands requires beingmaintained at a temperature of 5°C. You determine averagewater activity (aw) at this temperature to be 0.2.
One day, you are informed that the cooling systems onone of the delivery trucks carrying your company’s productsmalfunctioned while en route to its destination and it would notbe fixed until the next delivery. The driver has informed you thatthe temperature in the delivery bay of the truck is averaging55°C. You estimate a heat of sorption (Q) of 19 kJ/mol.
Calculate the water activity of the brand at this elevatedtemperature and comment on it’s integrity. Should the deliverystill push through? Or should the products be recalled anddisposed

Any botle that has more than two bubbles is elassified as "nonconforming" and is sent to recycling Suppose that a particular production line produces bottles with bubbles at a rate of 1. bubbles per bottle. Bubbles occur independently of one another. a What is the probability that a randomly chosen bottle is nonconfornming? b Bottles are packed in cases of 12. An inspector chooses one bottle from each case and examines it for defects. If it is nonconforming, she inspects the entire case, re placing nonconforming bottles with good ones. This process is called rectification If the chosen bottle conforms (has two or fewer bubbles), then she passes the cuse. In total, 20 cases are produced.
