Please answer asap and type your answer and do not copy from anywhere please There are important policy implications with regard to whether a test should be set to identify all people with a disease or condition; or set to identify all people without the disease or condition. The perfect test would of course do both. A 100% percent sensitive test would identify all persons with the disease; while a 100% specific disease would identify all without the disease or condition. Most tests are not 100% sensitive or specific, and therefore result in false positive and false negatives. Using a specific example of a disease or condition, state whether you believe the test for that disease or condition should be 100% sensitive or specific, and the implications for false negatives and false positives for that disease.

For the three-part question that follows, provide your answer to each question in the given workspace. Identify each part with a coordinating response. Be sure to clearly label each part of your response as Part A, Part B, and Part C.Part A: What is the term for a generalization made about a population using the data from a sample?Part B: Name one challenge that may occur when using a sample to draw a conclusion about a population.Part C: A researcher collects data about the annual salary of employees who work in the information technology field. It would be difficult to survey all employees, so a sample of the population is surveyed. The data is recorded below. Use the table to write one conclusion that can be drawn. Explain why this conclusion is valid. Salary Range (Per Year) Number of Employees $50,000-$59,999 147 $60,000-$69,999 159 $70,000-$79,999 225 $80,000-$89,999 27

The Computer Anxiety Rating Scale (CARS) measures an individual’s level of computer anxiety, on a scale from 20 (no anxiety) to 100 (highest level of anxiety). Researchers at a large university administered CARS to 80 business students. One of the objectives of the study was to determine whether there is a difference between the level of computer anxiety experienced by female students and male students. Of the 80 student survey takers, 40 were male, 40 were female. The results are in the table below for statistical analysis of variability between the two samples. All of these analyses are run with a 95% level of confidence. Males Females Sample Mean 40.26 36.85 Sample Standard Deviation 13.35 9.42 Perform the test chosen in part (d) of the previous problem and supply this information: a. What is the value of the test statistic? b. Find the probability of getting these results if there is no difference in anxiety ratings between the…

An investigator wants to assess whether smoking is a risk factor for pancreatic cancer. Electronic medical records at a local hospital will be used to identify fifty patients with pancreatic cancer. One hundred patients who are similar but free of pancreatic cancer will also be selected. Each participant’s medical record will be analyzed for smoking history. Identify the type of study proposed. Briefly explain why you think the study is of this type. Indicate the study type's specific strengths and weaknesses. What is the most likely source of bias in the study .

As part of a statistics project, a teacher brings a bag of marbles containing 800 white marbles and 300 red marbles. She tells the students the bag contains 1100 total marbles, and asks her students to determine how many red marbles are in the bag without counting them. A student randomly draws 100 marbles from the bag. Of the 100 marbles, 32 are red. The data collection method can best be described as Survey Census Controlled study Clinical study The target population consists of The 1100 marbles in the bag The 300 red marbles in the bag The 32 red marbles drawn by the student The 100 marbles drawn by the student None of the above The sample consists of The 300 red marbles in the bag The 32 red marbles drawn by the student The 100 marbles drawn by the student The 1100 marbles in the bag None of the above Based on the sample, the student would estimate that marbles in the bag were red.
