2. Calculating the price elasticity of demand: A step-by-stepguide Suppose that during the past year, the price of a virtual reality headset rose from $4,750 to $4,880. During the same time period, consumer sales decreased from 396,000 to 271,000 headsets. Calculate the elasticity of demand between these two price-quantity combinations by using the following steps. After each step, complete the relevant part of the table with the appropriate answers. (Note: For decreases in price or quantity, enter values in the Change column with a minus sign.) Original Quantity Price $ $ New Average Change Percentage Change Step 1: Fill in the appropriate values for original quantity, new quantity, original price, and new price. Step 2: Calculate the average quantity by adding the original quantity and the new quantity, and then dividing by two. Do the same for the average price. Step 3: Calculate the change in quantity by subtracting the original quantity from the new quantity. Do the same for the change in price. Step 4: Calculate the percentage change in quantity demanded by dividing the change in quantity by the average quantity. Do the same to calculate the percentage change in price. Step 5: Calculate the price elasticity of demand by dividing the percentage change in quantity demanded by the percentage change in price, ignoring the negative sign. Using the midpoint method, the elasticity of demand for headsets is about

A new weight-watching company, Weight Reducers International, advertises that those who join will lose an average of 10 pounds after the first 2 weeks. The population standard deviation is 2.8 pounds. A random sample of 50 people who joined the weight reduction program revealed a mean loss of 9 pounds. At the 0.05 level of significance, can we conclude that those joining Weight Reducers will lose less than 10 pounds? b. State the decision rule for 0.05 significance level. (Negative amount should be indicated by a minus sign. Round your answer to 2 decimal places.)

FIRST ACTIVITY (100/100) RANDOM MEMORY ACCESS (RAM) EMULATOR: The following circuit is a memory with 8 addresses, each address holding a 4-bit data. The memory positions are implemented by 4-bit registers. The setn (active low) and clock signals are shared by all the registers. Data is written onto (or read from) one of the registers. wr_rd 0 Memory Write wr_rd = 1 The 4-bit input Din is written into one register. The address[2..0] signal selects the register to be written. Here, the 7-segment display must show 0. Example: if address = 101, then Din is written into register 5. Decoder 3 Decoder: HEX to 7 segments A 4/ 4 Memory Read wr_rd = 0 The MUX output appears on the 7-segment display hex.value. The address[2..0] signal selects the register from which data is read. For example, if address = 010, then data in register 2 appears on the 7-segment display. If data in register 2 is 1010, then the symbol 'A appears on the 7-segment display. 5
