The figure shows a simple device for measuring your reaction time. It consists of a cardboard strip marked with a scale and two large dots. A friend holds the strip vertically, with thumb and forefinger at the dot on the right in the figure. You then position your thumb and forefinger at the other dot (on the left in the figure), being careful not to touch the strip. Your friend releases the strip, and you try to pinch it as soon as possible after you see it begin to fall. The mark at the place where you pinch the strip gives your reaction time. (a) How far from the lower dot should you place the 50.0 ms mark? How much higher should you place the marks for (b) 100, (c) 150, (d) 200, and (e) 250 ms? (For example, should the 100 ms marker be 2 times as far from the dot as the 50 ms marker? If so, give an answer of 2 times. Can you find any pattern in the answers?)

Figure 1 shows the schematic diagram of a mechanical system that consists of two subsystems in parallel. The first subsystem consists of two components A and B in series, both of which have the same 0.80 probability of working. The second subsystem consists of three components C, D, and E in series, all of which have the same 0.90 probability of working. It is assumed that all components of the system are independent. (a) What is the probability that subsystem...

Use R Studio to solve this problem. A simple electronic device consists of two components which have failure times which may be modeled as independent exponential random variables. The first component has a mean time to failure of 3 months, and the second has a mean time to failure of 6 months. (a) If the electronic device will fail when either of the components fails, use 1000 random samples of the simulated electronic device to estimate the mean and variance...

A food processing operation consists of mixing ingredients, forming and cooking. Figure below shows the cooking process where the formed material travels through a cooking oven on a conveyer belt. The raw material is subject to shrinkage due to the cooking process. The specification limits for shrinkage is between 5% and 9%. There are two machines operating two shifts daily. A technician selects samples before and after cooking process and calculates percent shrinkage. Table below shows the data set for...

Vernier scale. The figure below shows a scale found on instruments such as a micrometer caliper used for accurately measuring dimensions of objects. The lower scale slides along the upper scale and is used to interpolate between the markings on the upper scale. In (a) The reading (at the left-hand 0 of the lower scale) is between 1.4 and 1.5 on the upper scale. To find the exact reading, observe which mark on the lower scale is aligned with a...

Figure 1 shows the short-run effect of a drought in a given time period that affected harmfully the production of wheat in North Dakota. Assuming other things being equal, the wheat supply curve has shifted leftward from S1 to S2 causing equilibrium price to fall from P1=$330 per bushel to P2 = $400 per bushel, and equilibrium quantity to fall from Q1= 200 million bushels to Q2=190 million bushels. Referring to Figure 1, which of the following is true? Question...
