- A retail store sold in the month of April 5,000 products that produced $45,000 in sales. In the month of May the company sold 6,000 products. The store workforce consists of four full-time workers who work 40-hour week. In April the store also had seven part-time workers at 10 hours per week, and in May the store had nine part-timers at 15 hours per week (assume four weeks in each month). Using sales dollars as the measure of output (assume the price of the product was the same for both months), what is the percentage change in labor productivity from April to May?

They produce transcutaneus electrical nerve simulation units (TENS) for pain control. Amman faces a new opportunity and is not sure how to go about it. Recently, the the Department of Health of Canada has approved low current TENS devices to be sold directly to consumers without a doctor’s note. This will come into effect in three months. In the past, one needed a doctor’s note and could rent the device from some companies. These TENS machines, as they are called in Canada, are popular, since the older population has found them to be effective in pain control with almost no side effects. Amman can sell the device via drug-stores and pharmacies as well as on Amazon. But, Amman is not sure. Amman used to work as a supply chain manager for a power-tool company. Back then, it was a huge logistical “pain,” no pun intended, to work with large retailers and to attend to their fulfilment needs. Those retailers used to…arrow_forward
- Fire Department Turns to BI Analytics. New York City has nearly one million buildings, and each year, more than 3000 of them experience a major fire. The Fire Department of the City of New York (FDNY) is adding BI analytics to its arsenal of firefighting equipment. It has created a database of over 60 different factors (e.g., building location, age of the building, whether it has electrical issues, the number and location of sprinklers) in an attempt to determine which buildings are more likely to have a fire than others. The values of these parameters for each building are fed into a BI analytics system that assigns each of the city's 330,000 inspectable buildings a risk score. (FDNY doesn't inspect single and two-family homes.) Building inspectors then use these risk scores to prioritize which buildings to visit on their weekly inspections. The FDNY has roughly 350 inspectors who are trained and certified to perform their duties.Which set of three parameters all provide measures…arrow_forwardInvestment Manager: Works with the Investment Analyst to decide the number of stocks to be purchased, how much cash to hold and the timing of purchases.arrow_forwardA suburb of Dayton, Ohio, has four local dry cleaners that compete with each other on the basis of price and service speed.
