Tsunami Waves and BreakwatersThis is a continuation of Exercise 16. Breakwaters affect wave height by reducing energy. See Figure 5.30. If a tsunami wave of height H in a channel of width W encounters a breakwater that narrows the channel to a width w, then the height h of the wave beyond the breakwater is given by h=HR0.5, where R is the width ratio R=w/W. a. Suppose a wave of height 8 feet in a channel of width 5000feet encounters a breakwater that narrows the channel to 3000feet. What is the height of the wave beyond the breakwater? b. If a channel width is cut in half by a breakwater, what is the effect on wave height? 16. Height of Tsunami WavesWhen waves generated by tsunamis approach shore, the height of the waves generally increases. Understanding the factors that contribute to this increase can aid in controlling potential damage to areas at risk. Greens law tells how water depth affects the height of a tsunami wave. If a tsunami wave has height H at an ocean depth D, and the wave travels to a location with water depth d, then the new height h of the wave is given by h=HR0.25, where R is the water depth ratio given by R=D/d. a. Calculate the height of a tsunami wave in water 25feet deep if its height is 3feet at its point of origin in water 15,000feet deep. b. If water depth decreases by half, the depth ratio R is doubled. How is the height of the tsunami wave affected?
Q1 The owner of the ABC garment is interested to study the wastage of the factory. Factory is running in two shifts (morning and evening). The value of the monthly wastage of the material shift wise is given in the data file. The manager told to the owner that on average, the value of monthly (both shifts) wastage is Rs. 4500. The owner feels that the wastage is more than the value which is communicated by the manager; therefore, he gives the data of the last few months (given below) to you as statistician and assigns the following three tasks: Morning Shift 4227 4489 4417 4392 3943 3970 4405 4990 4444 4405 4398 4152 Evening Shift 3366 2964 3043 3804 3721 3675 3504 3236 3955 3420 Task # 1: To test the manager’s claim at 0.05 level of significance. Task # 2: To test the equality of mean wastage in two shifts, assume the variances are equal at 0.05 level of significance.…
Independent surveys show that the average IQ of 9 r/s babies exposed to cocaine in the uterus is 81 with s.d. 18, while the average IQ of 20 r/s babies unexposed to cocaine in the uterus is 99 with s.d. 9. Construct a 90% c.i. for the difference between the overall average IQs of exposed and unexposed babies. Assume that both populations are normal.

The car manufacturer Edison is the sole producer of electric cars in the market, selling to two different types of customers. All else equal, travelers (type t) prefer batteries that go longer distances between charges and are willing to pay for this luxury. Urban drivers (type u) do not require as great a battery. Edison knows the willingness-to-pay of each type, and that there are q percent of type ts in the market. The willingness-to-pay for each type for different battery sizes are, Vt(k = 100) = $160, 000, Vt(k = 60) = $80, 000, Vu(k = 100) = $100, 000, Vu(k = 60) = $60, 000, where k is the battery life in kilowatt hours (kWh). Producing 60 kWh battery costs $30,000, which is half the cost of a 100 kWh battery. (a) Edison showroom salesmen believe they can perfectly identify (1st/3rd-degree) which type of buyer walks through the door. Find the profit-maximizing prices (pi) and battery sizes (ki). What is Edison’s average profit per customer? (b) It turns out Edison salesmen are…
You give a final attempt to bring the effect of Size back into the equation by forcing the assumption of homoskedasticity onto your estimation. The results are as follows: cost^= = 7,311.17 + 3,985.20 × Reputation – 0.20 × Size (1,985.17) (593.65) (0.07)+ 8,406.79 × Dpriv – 416.38 × Dlibart – 2,376.51 × Dreligion (1,423.59) (1,096.49) (989.23) R 2=0.72, SER = 3,682.02Calculate the t-statistic on the Size coefficient and perform the hypothesis test that its coefficient is zero. Is this test reliable? Explain.
