- Suppose that 20% of the adult population in Palestine smoke cigarettes only, 15% smoke Argeeleh only, and 10% smoke both cigarettes and Argeeleh. Suppose that 15% of those who smoke cigarettes only have respiratory problems, 10% of those who smoke Agreeleh only have respiratory problems, 20% of those who smoke both cigarettes and Argeeleh have respiratory problems, and 5% of non-smokers have respiratory problems. If an adult person is randomly selected from the population: What is the probability that he/she has respiratory problems? If the selected individual has respiratory problems, what is the probability that he/she is non-smoker? If the selected individual has respiratory problems, what is the probability that he/she smokes both cigarettes and Argeeleh?Let's assume that there are 500 people in a population. The researcher has access to all 500 participants, and sends a questionnaire that is accessed by a hyperlink. Of the 500 possible subjects, 485 complete it. Does this mean that the results generated from this study will be highly-accurate? What might cause the study to be unreliable?Suppose a study investigated the effects of exercise and daily stretching to see how blood pressure was affected. 240 women volunteered to take part in the study. In the study, participants were randomly assigned to one of 3 different exercises plans (Plan A, Plan B, or Plan C) and they were randomly assigned to one of 2 different stretching plans (Plan 1 or Plan 2). a. Identify the subjects. b. Identify the factor(s) and number of level(s) for each. How many treatment groups are there?
- Thank you for your feedback on part b. Per your instruction, re-posting question part a. I need help visualizing a tree diagram for this problem. Thank you in advance. Question: A family wants to adopt pets from the local animal rescue. They have prepared a final list of five, all of whom are healthy. Of the five animals, one is a cat and four are dogs. The family decides to select two animals randomly from these five possibilities. a.) Draw a tree diagram to show all possible outcomes of this selection process. Label the probability associated with each stage of the selection on the appropriate branch. Make a table with the outcomes and the probability of each outcome.Is there a link between dark chocolate and weight loss when compared to milk chocolate? A nutritionist gathers 60 people, selected at random, then randomly assigns half of the group to eat a single dark chocolate bar after dinner each night and the other half to eat a single milk chocolate bar after dinner each night for 6 months. Everyone is to keep track of the other food they eat in an app provided. The nutritionist then compares each person’s weight after the 6 months to their weight before eating the different chocolates accounting for the other calories consumed. 12) What type of study does this describe? a) Survey b) Observational study c) Experimental studyIf the studies are inconsistent, it means that at least some of the age group from the first study will not be included in the second study, or some of the age group from the second study will not be in the first study. Therefore, to determine if the two studies are inconsistent in their description of generation A we must compare the age groups from the two studies to see if either one includes people not included in the other study. In other words, we need to determine if the age ranges match up exactly when the year of the study is taken in to consideration. In the first study from 2005, generation A is defined to be people ages 17–28. Three years later, in 2008, the second study was published and defined generation A to be people ages ages 20–31. a) First we examine the low end of the age ranges. We note that someone who was 17 years old in 2005 would be ______ years old in 2008. b) Now we examine the high end of the age ranges. We note that someone who was 28 years old in 2005…
- 1.) This is not an incomplete question. It has all the components of the question that was asked. Please help explain. Need help from a prob and stats expert: Let arr86 be a binary variable equal to 1 if a man was arrested during 1986, and zerootherwise. You have a dataset of young men from California who were born in 1960 or1961 and have at least one arrest prior to 1986. You also have data on the proportion ofprior arrests that led to a conviction (pcnv), the average sentence served from priorconvictions in months (avgsen), months spent in prison since age 18 prior to 1986(tottime), months spent in prison in 1986 (ptime86), and the number of quarters (0 to 4)that the man was legally employed in 1986 (qemp86). You estimate the following linearprobability model (standard errors are in parentheses): The Standard Errors for the equation go in order for each independent variable of the equation, and are below. The equation is extended and is in two separte rows. All information is…A 2 X 3 factorial design has two variables that divide the groups. six variables that divide the groups. hree variables that divide the groups. "could be any of the above, depending on the number of measured variables"If two states are selected at random from a group of 10 states, determine the number of possible outcomes if the group of states are selected with replacement or without replacement. If the states are selected with replacement, there are possible outcomes.
- Exercise 6.4 Suppose you are interviewing 25 people in order to fill 5 job vacancies. How many possible choices of 5 people are there to fill those vacancies?A person, Joe, claims to be able to "smell" an illness based on the odor of a person's clothing. Joe is given 12 shirts, each worn by a different person, some of whom had the illness and some of whom did not. The shirts were given to Joe in random order and he had to decide whether each shirt had been worn by an ill patient or by a healthy patient. joe identified 11 of the 12 shirts correctly. If we assume that Joe was just guessing, he would have probability 1/2 of correctly identifying each shirt. Find the probability that Joe would identify AT LEAST 11 shirts correctly by random guessingSpam Email Filters. A study by Forbes indicated that the five most common words appearing in spam emails are shipping!, today!, here!, available, and fingertips!. Many spam filters separate spam from ham (email not considered to be spam) through application of Bayes' theorem. Suppose that for one email account, 1 in every 10 messages is spam and the proportions of spam messages that have the five most common words in spam email are given below. shipping! 0.051 today! 0.045 here! 0.034 available 0.014 fingertips! 0.014 Also suppose that the proportions of ham messages that have these words are: shipping! 0.0015 today! 0.0022 here! 0.0022 available 0.0041 fingertips! 0.0011 a. If a message includes the word shipping!, what is the probability the message is spam? If a message includes the word shipping!, what is the probability the message is ham? Should messages that include the word shipping! be flagged as spam? b. If a message includes the word…
