- What does a G01 tell a machine to perform?A Bitter Dispute With the publication of Ars Magna, a dispute intensified between Jerome Cardan and another mathematician named Niceolo Fontana, otherwise known as Tartaglia. What was the dispute, and how did it arise? In your opinion, who was at fault? Write a paragraph or two about your findings.Arthritis is a very commonly occurring affliction. It is a major cause of lost work time and often results in serious disability. Of the many types of arthritis, the most common type is osteoarthritis. This condition is frequently due to wear and tear in the joints and is more likely to be found in people over 50. It is very painful in the weight-bearing joints, such as the knees and hips. Cartilage wears away on the bone ends, causing pain and swelling. Osteoarthritis may develop after an injury such as a bone fracture or a joint dislocation. To reduce the amount of time osteoarthritis patients are absent from work, it is important for them to have effective pain relief. An experiment was conducted to compare the effectiveness of three new analgesics: A1, A2, and A3. A clinic evaluated a large group of patients and identified 45 patients with a moderate level of pain. Fifteen of the 45 persons were then randomly assigned to one of the three analgesics. The patients were then…
- Dairy cattle are cattle that are bred for their ability to produce large quantities of milk. Lameness is a condition that can be detrimental to cattle since it can be painful and result in deleterious effects on the animal’s welfare. It is a condition in which cows have difficulty moving and especially walking. Investigators are interested in whether milk production in dairy cows is associated with whether or not the cow becomes lame. They think that the age of the cow (young or old) may confound and/or modify the relationship between milk production and lameness and so they collect information on the age of the cows as well. The data that cross classifies lame status and milk production status is stratified by age and provided in the tables below. Use SAS to complete each part. (a) Ignoring age, report the estimate for the OR and its corresponding 95% confidence interval. Interpret both. (b) Ignoring age, is milk production associated with lameness? Justify your response using a…We want to know if students with bronchitis at 5 years have more cough symptoms when they grow up. Out of 290 children with Bronchitis at Age 5, 32 of them has cough symptoms at Age 12. Out of 970 children with no Bronchitis at Age 5, 43 of them has cough symptoms at Age 12. Is the cough symptom equally prevalent in both populations?A soda company sells one of its soft drinks in 12 ounce cans. In order to ensure that every can has at least 12 ounces in it, the machines in the factory are set to fill each can with an average of 12.1 ounces of soda. Every week, a quality-control technician tests 10 cans to make sure that the average amount of soda in the cans is still 12.1 ounces. If the conclusion of the test is that the number of ounces of soda in the cans is different from 12.1, the technician will declare that the process is out of control, and the machine will be stopped and calibrated. From previous tests, the technician found that the standard deviation of the number of ounces of soda in the cans is approximately 0.01. The number of ounces of soda in the 10 cans that were tested this week is given below. Assume that the standard deviation from the technician's previous tests is the population standard deviation. Use a TI-83, TI-83 Plus, or TI-84 calculator to test whether filling process is out of control and…
- excerpt from “Shoes: Feet First!”from A History of Travel in 50 Vehiclesby Paula Grey & Phillip Hoose Despite the relatively recent age of the early shoes found to date, scientists believe that humans were wearing shoes as much as 40,000 years ago. Shoes made of reeds, papyrus, or even leather decompose easily, leaving few or no traces. But people who don’t wear shoes have wider feet and bigger gaps between their big toe and the other four. In studying bones of the smaller toes of fossilized skeletons, scientists observed that the thickness of these bones decreased somewhere between 40,000 and 26,000 years ago. They believe the change was the result of wearing shoes. 1 Select the correct answer. Read this sentence again. In studying bones of the smaller toes of fossilized skeletons, scientists observed that the thickness of these bones decreased somewhere between 40,000 and 26,000 years ago. How does the sentence develop the author’s claim in the passage?…To the Internal Revenue Service (IRS), the reasonableness of total itemized deductions depends on the taxpayer's adjusted gross income. Large deductions, which include charity and medical deductions, are more reasonable for taxpayers with large adjusted gross incomes. If a taxpayer claims larger th average itemized deductions for a given level of income, the chances of an IRS audit are increased. Data (in thousands of dollars) on adjusted gross income and the average or reasonable amount of itemized deductions follow.

Does this mean that very good grades are a handicap for those seeking high incomes? What other factors might cause this result?
- PLEASE DON'T UPLOAD A PICTURE OF THE ANSWER. PLEASE TYPE IT SO I CAN COPY AND PASTE IT INTO MY NOTES. THANK YOU!! Chi-Square Good of Fit Problem: Automobile insurance is much more expensive for teenage drivers than for older drivers. To justify this cost difference, insurance companies claim that the younger drivers are much more likely to be involved in costly accidents. To test this claim, a researcher obtained information about registered drivers from the Department of Motor Vehicles (DMV) and selected a sample of n = 300 accidents reports from the police department. The DMV reports the percentage of registered drivers in each age category as follows: 16% are younger than age 20,; 28%are 20 to 29 years old;and 56% are age 30 and older. The number of accidents reports for each age group is as follows: Under age 20 Age 20-29 Age 30 and older 68 92 140 Is…Please help needed on this asap. Thanks so much! It has been observed that some persons who suffer colitis, again suffer colitis within one year of the first episode. This is due, in part, to damage from the first episode. The performance of a new drug designed to prevent a second episode is to be tested for its effectiveness in preventing a second episode. In order to do this two groups of people suffering a first episode are selected. There are 170 people in the first group and this group will be administered the new drug. There are 132 people in the second group and this group wil be administered a placebo. After one year, 14% of the first group has a second episode and 18% of the second group has a second episode. What is a 90% confidence interval for the difference in true proportion of the two groups.A researcher wants to know why individuals in Community A have a higher rate of a rare form of cancer when compared to those living in Community B. To find out the reasons for the differences in cancer rates in these two communities, the investigator surveyed residents about their lifestyle, noted the types of businesses that were present in the community and searched medical records. The researcher found that the headquarters for the Toxico Chemical Plant is located in Community A, there is a higher rate of cigarette smoking in this community and residents tended to delay or skip going to the doctor for an annual checkup. In Community B, the largest employer was a department store and on average, residents did not smoke as much as residents from Community A. However, like individuals from Community A, Community B residents tended to delay or skip their annual checkup with their doctor. 1. What makes this a descriptive study?
