Get help for Davenport-University STAT 500 Homework Help. What is being tested when the Goodness-of-Fit test is used to analyze the data? Which of the following occurs when the chi square value is small? If the chi square test suggests that you should fail to reject H0, what can you conclude? The table below summarizes results from an experiment in which subjects were classified as diabetic or nondiabetic and then given a treatment. After the treatment, they were again classified as diabetic or nondiabetic. Which combinations of before treatment/after treatment categories will yield discordant pairs? The table below summarizes results from an experiment in which subjects were classified as asthmatic or nonasthmatic and then given a treatment. After the treatment, they were again classified as asthmatic or nonasthmatic. How many subjects were included in the experiment? A bag contains 4 red marbles, 3 blue marbles, and 7 green marbles. If a marble is randomly selected from the bag, what is the probability that it is blue?
Of 1,735 people who came into a blood bank to give blood, 373 people had high blood pressure. Estimate the probability that the next person who comes in to give blood will have high blood pressure. Find the indicated probability. Provide a written description of the complement of the given event. Of ten adults, at least one of them has high blood pressure. Answer the question, considering an event to be “unusual” if its probability is less than or equal to 0.05. Assume that one student in your class of 23 students in randomly selected to win a prize. Would it be “unusual” for you to win? Use the range rule of thumb to identify a range of values containing the usual number of peas with green pods given the following: ? 1.2 peas Based on the result, is it unusual to get only one pea with a green pod?
To met the requirements of a probability distribution, only ONE of the following must be met: 1. The sum of all probabilities must be equal to 1. 2. Each probability value must be between 0 and 1 inclusive. The probabilities that a batch of 4 computers will contain 0, 1, 2, 3, and 4 defective computers are 0.4979, 0.3793, 0.1084, 0.0138, and 0.0007, respectively. Find the mean of the given probability distribution. Round your answer to the nearest hundredth. The probabilities that a batch of 4 computers will contain 0, 1, 2, 3, and 4 defective computers are 0.4979, 0.3793, 0.1084, 0.0138, and 0.0007, respectively. Find the standard deviation for the given probability distribution. Round your answer to the nearest hundredth. Determine whether the given procedure results in a binomial distribution. If not, state the reason why. Choosing 5 people (without replacement) from a group of 34 people, of which 15 are women, keeping track of the number of men chosen. 1 One objective of this course is learning how to correctly interpret statistical measures. This includes learning how to identify intentionally misleading statistics. For this week’s activity create your own example of a misleading statistic.
2 Wondering how an Introduction to Statistics course will help you in your job, especially if your hopes for this class are to just survive? To get an idea of how statistics is used in your field, interview a colleague to find out how he or she uses statistics in his or her job. How do you use statistics in your job and what specific statistical concepts do you use? 2. Please describe a specific example of how the use of statistics was helpful in improving a practice or service. 3. What background in statistics is required to obtain a job like yours? What other educational requirements are there? Do you recommend that today’s college students study statistics? Why or why not? Comment on what you learned from the interview or what was most interesting or surprising to you. 3 the mathematical expression of probability as a number between 0 and 1 is fundamental to understanding statistics. Define and interpret the rare event rule for inferential statistics. This means that you should summarize from the text and then provide your own understanding of the reare event rule. Find an article from a peer-reviewed journal that states the p-value. What is the p-value? What does the p-value tell us? What is the author’s conclusion based on that probability?
