The Food and Drug Administration (FDA) oversees the approval of both medical devices and new drugs. To gainFDA approval, a new device must be shown to perform at least as well, and hopefully better, than any similardevice already on the market. Suppose a medical device company develops a new system for connectingintravenous tubes used on hospital patients. To be comparable to an already-existing product, the force requiredto disconnect two tubes joined by the new device must not exceed 5 lb. To estimate the maximum force requiredto disconnect two tubes, several tests are made. For a random sample of n connections, the forces X₁1, X2, X3, . . . ,Xn required to disconnect the tubes are recorded and the maximum, M, of the n readings is used to estimate themaximum necessary force for all such connections....Suppose that the actual distribution of forces needed to disconnect tubes can be described by a uniformdistribution on the interval [2, 4]. For a sample of size n = 2, do you expect the mean of the samplingdistribution of M to be closer to 2 or 4?

Here we are drawing a random sample of size 2 from U[2, 4] which represents the forces required to…

Assume that the production of 1 unit of magnesium requires 0.8 units of magnesium and 0.2 units of aluminum, and that the production of 1 unit of aluminum requires 0.3 units of magnesium and 0.2 units of aluminum.
Robert sold used cars, but he had little or no knowledge with respect to technical aspects of any of the vehicles that he sold. Ray was seeking to buy a Honda Civic and Robert gave his opinion as to the speed of the car and its durability. Ray subsequently finalized the purchase and took control of the car. Two weeks after the purchase, the Honda Civic broke down and required extensive mechanical repairs. Ray is angry and is of the view that Robert misrepresented the condition of the car when he sold it. Ray is of the opinion that as a used car Salesman, Robert should have known that the car was indeed in poor mechanical condition. Ray knows that you are studying Business law and sought your advice on the matter USING THE IRAC method of legal reasoning. please advice Ray.

The profitability of the leading cola syrup manufacturers PepsiCo and Coca-Cola and of the bottlers in the cola business is very different. PepsiCo and Coca- Cola enjoy an 81 percent operating profit as a percentage of sales; bottlers experience only a 15 percent operating profit as a percentage of sales. Perform a Porter’s Five Forces analysis that explains why one type of business is potentially so profitable relative to the other.
Assume that you are given a set of points and you want to find the regression line for this data. In other words, you are given a linear system Xa Y with no solution and you want to find a vector a such that Xa is the vector in the column space of X closest to Y in the Euclidean norm. Explain how to solve this problem using a QR factorization of X.
A new type of crank for bicycles called the Powercam relies on a pushing motion rather than a circular motion. The company that markets this crank plans a test of five riders who will travel a 100-mile route once with the Powercam and once with a conventional crank. The company claims that the new crank reduces the time needed to cover the 100 miles. The times in hours for the five riders are 3. as follows: Rider 1 3 4 5 Powercam 4.4 4.6 4.7 4.8 4.9 Conventional 5.1 5.3 5.1 4.9 5.2 Use a 5% significance level and assume that both population distributions are normal. Is there sufficient evidence in the data to support the claim that the new crank reduces the time needed to cover the 100 miles? (Hint: Follow the steps 1) identify the case; 2) set the alternative hypothesis; 3) set the null hypothesis; 4) find the rejection region; 5) calculate the test statistic; and 6) make decision.)

In laparoscopic surgery, a video camera and several thin instruments are inserted into the patient's abdominal cavity. The surgeon uses the image from the video camera positioned inside the patient's body to perform the procedure by manipulating the instruments that have been inserted. It has been found that the Nintendo Wii™ reproduces the movements required in laparoscopic surgery more closely than other video games with its motion‑sensing interface. If training with a Nintendo Wii™ can improve laparoscopic skills, it can complement the more expensive training on a laparoscopic simulator. Forty‑two medical residents were chosen, and all were tested on a set of basic laparoscopic skills. Twenty‑one were selected at random to undergo systematic Nintendo Wii™ training for one hour a day, five days a week, for four weeks. The remaining 21 residents were given no Nintendo Wii™ training and asked to refrain from video games during this period. At the end of four weeks, all 42 residents…
