- Explain the differences between Gaussian elimination and Gauss-Jordan elimination.A disease can be caused by three strains of a virus. Suppose that Type A is statistically the most widespread causing 85% of all cases, Type B causes 12% of cases and Type C causes the remaining cases. a standard course of medication XYZ is enough to treat 90% of cases caused by Type A, 30% of cases caused by Type B and 4% of cases caused by Type C. If a patient’s symptoms do not improve after a course of XYZ, how likely is it that their case is caused by strain of Type NA particular two-player game starts with a pile of diamonds and a pile of rubies. Onyour turn, you can take any number of diamonds, or any number of rubies, or an equalnumber of each. You must take at least one gem on each of your turns. Whoever takesthe last gem wins the game. For example, in a game that starts with 5 diamonds and10 rubies, a game could look like: you take 2 diamonds, then your opponent takes 7rubies, then you take 3 diamonds and 3 rubies to win the game.You get to choose the starting number of diamonds and rubies, and whether you gofirst or second. Find all starting configurations (including who goes first) with 8 gemswhere you are guaranteed to win. If you have to let your opponent go first, what arethe starting configurations of gems where you are guaranteed to win? If you can’t findall such configurations, describe the ones you do find and any patterns you see.
- AJ’s sleep pattern had been fluctuating due to stress and diet, so he started to keep a diary of how many hours he slept each night. On the 4th night after he started the diary, AJ slept 9.4 hours, which was the most sleep he got any night. Gradually, he got less sleep each successive night until, on the 18th night after he started the diary, AJ slept 6.2 hours, which was the least sleep he got any night. After keeping his diary for 6 months, he realized that the number of hours he got each night followed a sinusoidal curve. Let t be the number of nights since he started his diary, and s be how many hours he slept that night. It may be helpful to draw a crude sketch of the sleep time function and label the known t − and s − values on it. POSITIVE or NEGATIVE SIN or COS Maximum s − value = Minimum s − value = ______________ ______________ Middle s − value = ______________ = D Amplitude = ______________ = A ⇒ B = ______________ Given the crude sketch of the height function, the…How does expressed symbolically between-rows sum of squares?A case-control study is being planned to see whether proximity to a nuclear power plant is associated with the development of certain cancers. 200 cases and 200 controls will be recruited and the distance from the nearest nuclear power plant will be dichotomized as close (< 3 miles) or far (≥ 3 miles). Use SAS to complete each problem below. (d) Since investigators find it very difficult to recruit cases, they decide to recruit three times as many controls as cases. How many cases and controls will they need to recruit in order to have 80% power? (Still assume a 2-sided, 5% level test, the same exposure probability among controls, and same OR.) If everything stays the same as above but the level of the test is reduced below 5%, what would happen to the total sample size computed first? (e) It is believed that about 4% of controls live close to the plant and the OR that investigators would be interested in detecting is 3.5. Assuming that a 2-sided, 5% level test will be…
- Explain the concept and use of the method of Least SquaresTwo computer programs are designed to perform certains tasks. Each time you have a new task, you make both programs handle it, and then check which of the two works better. You are aware that one of the programs outperforms the other in 60 percent of the cases and underperforms in 40 percent of the cases (each time independently of what happens in the other cases). However, you don’t know which of the two programs is better(you could probably figure it out by having them both work on a large number of tasks but that would take very long). (a) What is the probability that the same program outperforms on both of the next two tasks?(b) Given that the first program outperformed on the last two tasks, what is the probability that the first program is the better one of the two? (Hint: use the Bayesformula.)(c) Given that the first program outperformed on the last two tasks, what is the probability that it will outperform on the next one?While you are on a 4-week vacation, you will play at least one set of tennis matches each day, but you wouldn’t play more than forty sets total during this time. Prove that no matter how you distribute your games during the four weeks, there is a span of consecutive days during which you will play exactly 15 games.
- A farmer wishes to determine which of two brands of baby pig pellets, Kent or Moormans, produces better weight gains. Two of his sows each give birth to litters of 10 pigs on the same day, so he decides to give the baby pigs in litter A only Kent pellets, while the pigs in litter B will get only Moormans pellets. After 4 weeks , the average weigh tgain for pigs in litter A is greater than the average weight gain for pigs in litter B. The feed they get is not the only factor affecting the rate at which pigs gain weight. Genetic differences also affect weight gain. It is likely that the pigs in litter A are genetically different from the pigs in litter B since the two litters have different mothers. What experimental design technique could the farmer use to take into account the genetic differences? A)placebo B) probability sampling C)Blocking D)observational study E)double-blindingA cognitive psychologist is interested in the effect that sleep has on daily stress levels. To investigate this, the psychologist recruits 88 participants and splits them equally into either a group that gets less than six hours of sleep each night or a group that gets more than six hours of sleep each night. At the end of each day, participants are asked to report their overall level of stress each day for a month. Those who had fewer than six hours of sleep on average reported stress levels of 6.3 (with most people falling within 1.7 hours of this average). However, those who had more than six hours of sleep reported stress levels of 3.5 (with most people falling within 2.8 hours of this average). Help the psychologist estimate the difference in stress levels based on amount of sleep. What would be the smallest amount of difference in stress in two populations that either got more or less than six hours of sleep? Does this study meet an assumption of HOV? For this study, what kind…An educational software company wants to compare the effectiveness of its computer animation for teaching biology with that of a textbook presentation. The company gives a biology pretest to each of a group of high school juniors, and then divides them into two groups. One group uses the animation, and the other studies the test. The company retests all students and compares the increase in biology test scores in the two groups b. If the group using the computer animation has a much higher average increase in test scores than the group using the textbook, what conclusions, if any, could the company draw
