- You are given five different data points, p1, p2, p3, p4, p5. Use the similarity matrix in Figure 2 to perform complete link hierarchical clustering. a) For each of the four merging steps, show the updated proximity matrix of the clusters. b) Visualize the clustering solution using a dendrogram. The dendrogram should clearly show the order in which the points are merged, and the distances between the clusters merged. c) Which clusters are formed we need to have two clusters? Note: while the proximity table that is given to you has similarities, you can easily transform them into distances if you compute d = 1 - s. p1 p2 p3 p4 p5 p1 1.00 0.10 0.41 0.55 0.47 0.35 0.98 Figure 2: Proximity matrix (similarity) p2 0.10 H 1.00 0.64 p3 0.41 0.64 1.00 0.44 0.85 L p4 0.55 0.47 0.44 p5 0.35 0.98 0.85 0.76 1.00 1.00 0.765. A technician suspects that one or more processors in a distributed system is not working properly. The processors, A, B, and [10] C, are all capable of reporting information about the status of the processors in the system (either working or not working). The technician is unsure whether a processor is really not working, or whether the problem is in the status reporting routines in one or more of the processors. After polling each processor, the technician receives the following status reports: • Processor A reports that Processor B is not working and Processor C is working. • Processor B reports that Processor A is working if and only if Processor B is working. • Processor C reports that at least one of the other two processors is not working. (a) Let a = "A is working," b = "B is working," and c = "C is working." Write the three status reports in terms of a, b, and c, using the symbols of formal logic. (b) Assume that all of the status reports are true, which processor(s) is/are…A company wanted to test whether an employee could detect the presence of an alarm in a certain environment. There are 30 trails, divided evenly with presence and absence of the alarm. The employee indicated the presence of the alarm 16 times, but he was only correct 13 times. a) Create a decision/response matrix that reflects all the participant responses. b) Compute the (i) hit, (ii) false alarm, (iii) correct rejection, and (iv) miss rates. c) Another employee also took part in the test, he had a hit rate of 0.82 and a false alarm rate of 0.15. Compare these two employees in terms of the d' and ß.
- The structure of a two-factor study can be presented as a matrix, with one factor determining the rows and the second factor determining the columns. With this structure in mind, identify the three separate hypothesis tests that make up a two-factor ANOVA, and explain the purpose of each test. Describe the mean differences that are evaluated by each of the three hypothesis test.(Devore: Section 3.2 #15) Many manufacturers have quality control programs that include inspec- tion of incoming materials for defects. Suppose a computer manufacturer receives circuit boards in batches of five. Two boards are selected from each batch of inspection. We can represent possible outcomes of the selection process by pairs. For example, the pair (1,2) represents the selection of boards 1 and 2 for inspection. (a) List the ten different possible outcomes. (b) Suppose that boards 1 and 2 are the only defective boards in a batch. Two boards are to be chosen at random. Define X to be the number of defective boards observed among those inspected. Find the probability distribution (pmf) of X. (c) Let F denote the cdf of X. Determine F(0), F(1) and F(2); then obtain F(x) for all other x.Where is the decision tree and how do I fold it back?
- ↑ The 1990 census reported that 32% of the households in Middletown were homeowners and the remainder were renters. During the next decade, 10% of the homeowners became rent and the rest continued to be homeowners. Similarly, 14% of the renters became homeowners and the rest continued to rent (A) Fill in the appropriate transition matrix for this process. Homeowners Homeowners Renters Renters AR NEHydroxychloroquine is a drug sometimes used to treat malaria or rheumatoid arthritis. This drug has recently received some notoriety as a possible treatment for those suffering from Covid-19. A hydroxychloroquine tablet comes in a 200 mg strength, but hydroxychloroquine dosage may be anywhere from 200 to 1200 mg. Thus, a patient must take multiple pills. Suppose X is the number of pills taken by a randomly selected hydroxychloroquine patient. Then according to JJSDA, x has the following probability mass function, p(x), and cumulative distribution function F(x). 1 2 4 p(x) .04 .27 .35 .10 07 F(x) .04 .31 a .83 .93 1 a. If F is the cumulative distribution function of x, then what is the value of a? b. If p is the probability mass function for x, then evaluate b. c. What is the expected value of x? d. Calculate the variance of x. e. What is the variance of 0.7*x? f. The CDC 'randomly' checks the dosage of 10 hydroxychloroquine patients. What is the probability that exactly 4 of the…A medical researcher conducted an observational study to understand the recovery rate forpatients infected with the COVID-19 in Malaysia. The researcher contacted thirteen COVID-19 survivors and interviewed them regarding their recovery experience. Two of the questionsasked are the recovery period (in days) and the number of days that have passed since receivingthe second dose of COVID-19 vaccine prior to infection. The recorded data is summarized as i) Identify the dependent variable in the study. ii) Calculate the correlation coefficient and interpret its value. iii) Estimate the regression model parameters and write the estimated linear regressionmodel. iv) Based on your answer in iii), predict the recovery period if a person is infected withCOVID-19 after 200 days of receiving second dose of COVID-19 vaccine. v) Table 1 represents the incomplete ANOVA table of the study. Find the values of P, Q,R and S. vi) Test the linearity between the two variables at 4% significance level.

The bank's operations manager wants to Improve front-office employee scheduling during the lunch hour (12:00-13:00) period. The manager starts with studying the customer walting times at the two branches and collects data for two groups of 35 customers at each branch. Customers at the business-center branch walted on average 3.8 minutes, whle those at the residential branch waited 4.4 minutes on average, Assume that the population standard deviations are 1.8 (business-center branch) and 2.5 tresidential branch). a. Considering the real-ife problem, determine the point estimate of the unknown quantity that needs to be estimated. (Round to two decimal places.) b.
