**Answer the following:**1. **Electric Consumption Question:** According to the records of an electric company serving the Boston area, the mean electric consumption for all households during winter is 1650 kilowatt-hours per month. Assume that the monthly electric consumptions during winter by all households in this area have a normal distribution with a mean of 1650 kilowatt-hours and a standard deviation of 320 kilowatt-hours. What percentage of the households in this area have a monthly electric consumption of 1851 to 1937 kilowatt-hours? Round your answer to two decimal places. **P =** [Textbox]2. **Supermarket Promotion Question:** The management of a supermarket wants to adopt a new promotional policy of giving a free gift to every customer who spends more than a certain amount per visit at this supermarket. The expectation of the management is that after this promotional policy is advertised, the expenditures for all customers at this supermarket will be normally distributed with a mean of $110 and a standard deviation of $25.64. If the management decides to give free gifts to all those customers who spend more than $160 at this supermarket during a visit, what percentage of the customers are expected to get free gifts? Round your answer to two decimal places. **[Textbox]** % of the customers are expected to get free gifts.3. **Car Dealership Question:** One of the cars sold by Walt's car dealership is a very popular subcompact car called the Rhino. The final sale price of the basic model of this car varies from customer to customer depending on the negotiating skills and persistence of the customer. Assume that these sale prices of this car are normally distributed with a mean of $19600 and a standard deviation of $360. Round your answers to 2 decimal places. a. Dolores paid $19154 for her Rhino. What percentage of Walt’s customers paid less than Dolores for a Rhino? **[Textbox]** % b. Cuthbert paid $20118 for a Rhino. What percentage of Walt’s customers paid more than Cuthbert for a Rhino? **[Textbox]** %4. **Hockey Pucks Question:** The pucks used by the National Hockey League for ice hockey must weigh between 5.5 and 6.0 ounces. Suppose the weights of pucks produced at a factory are normally distributed with a mean of 5.63 ounces
