Rolling blackouts have become a way of life in mainy major cities around the world. With electrical demandfar outstripping production, grid operators have come to rely on this systematic means of keeping thedistribution system from experiencing complete failure. In one city, the blackout schedule has esch regionwithout power on average. 2.5 hours per day. The standard deviation of blackout times in this ciry in 0.31hour. A local hospital in the area purchases a generator that will provide power to nonessential systema for3.5 hours. If the blackout times follow a normal distribution. what percentage of time will the borpital finditself without power to these nonessential systems?99.94%1.000%0.06%3.23%

Question A - A company producing steel nails receives an order for 5000 nails of length 50 mm. Due to externalfactors such as temperature and pressure, the lengths of the nails produced by the machine is normallydistributed with a standard deviation of 1.6 mm. Acceptable lengths (lengths that any customer willconsent to buy) must have a tolerance of 2 mm. If the machine is set to produce nails with a meanlength of 5.0 cm, determine the percentage of nails that are acceptable. A. 0.7888 / B. 0.8877 / C. 0.9921 / D. 0.7878 Further to the information provided in question A above, we are informed that nails produced thatare shorter than the minimum acceptable length have to be scrapped. Consider that 4.8cm is still theminimum threshold for acceptable nail length. If the cost to produce one nail is 45 cents, how muchdoes the company incur in Rand losses due to scrapping? A. R247.70 / B. R347.91 / C. R237.60 / D. R471.99 Further considering information given in questions A and question B, if…
please answer both questions within 30 minutes. its urgent. The Home and Garden (HG) chain of superstores imports decorative planters from Italy. Weekly demand for planters averages 1,500 with a standard deviation of 800. Each planter costs $10. HG incurs a holding cost of 25% per year to carry inventory. HG has an opportunity to set up a superstore in the Bakersfield region. Each order shipped from Italy incurs a fixed transportation and delivery cost of $10,000. Consider 52 weeks in the year. If the delivery lead time from Italy is 1 week and HG wants to provide its customers a cycle service level of 90%, how much safety stock should it carry? 1,025 1,776 1,940 2,253 A firm sells electronic components through catalogs.

A certain manufacturer makes 400w light bulbs. Assume that these light bulbs have lifetimes that are normally distributed with a mean lifetime of 480 hours and a standard deviation of 50 hours. Use this table or the ALEKS calculator to find the percentage of light bulbs with lifetimes shorter than 384 hours. For your intermediate computations, use four or more decimal places. Give your final answer to two decimal places (for example 98.23%). % X Español

Please review Section 9.2. A marketing researcher wants to estimate the mean amount spent per year ($) on a web site by membership member shoppers. Suppose a random sample of 100 membership member shoppers who recently made a purchase on the web site yielded a mean amount spent of $60 and a standard deviation of $56. Use technology to solve and include files and/or screen shots. Is there evidence that the population mean amount spent per year on the web site by membership member shoppers is different from $52? a =0.05 H:µ= 52 H : µ # 52 Identify the critical value(s): (Round to two decimal places as needed.)
