Suppose we learned a tree on a dataset and learned a tree with the followingdecision boundary. The image also shows the training examples used to learn thetree with "+" indicating positive label while "-" indicating negative.For this question, we are interested in using the tree learned from this data to predictthe probability a point has a positive label. Using this tree, what is the predictedprobability that the label is positive for the input (x[1] = 4, x[2]=2)? Enter youranswer as a number between 0 and 1 (rounded to two decimal places)x[2]4320.87234x[1]

Given information: There are two training examples with "+" indicating positive label and "-"…

Set your utility for $0 to be 0 and $1 million to be 100. Apply the simple decision tree used in determining your utility for money, where the lottery has a prize of $1 million if you win and $0 if you lose, to determine your utility for $500,000 and $200,000. Use these 4 utilities to draw your utility curve for money.
In a regression problem with 2 input variables, we construct a classification tree with 4 terminal nodes. This means（multiple choices) There was either four splits in only one of the input variables or one split in each of the input variable. There was a split in one of the input variables and no splits in the other. There was a split in each input variable. There was either a split in each input variable or three splits in only one of the input variables. There were 2 splits in each of the input variables.

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.

A psychologist wants to test the influence of color on object recognition in 4-year olds. She recruits 25 children and shows them two sets of pictures of everyday objects (variable = picture type), has the children name them, and measures the time it takes (variable = reaction time). She shows the children a color set of pictures first and then shows them a black and white set of pictures. a) What is the independent variable? b) What is the dependent variable? c) What is the second independent variable? d) What is the second dependent variable? e) Is "picture type" a within-subjects or between-subjects variable? f) What scale of measurement is reaction time? g) What scale of measurement is picture type? h) The order of presentation of the picture sets is what kind of variable?
A social and personality psychologist thinks that creativity differs by personality traits, rather than the traditional view that it is a cognitive process. Specifically, this psychologist thinks that introverts are more creative than extraverts. The researcher gives a personality test to a group of 16 university students and then separates them based on the assessment results into 2 groups: the extraverts and the introverts. The participants are then asked to write a short story which is rated on creativity by a well-known author. The creativity scores range from 0 to 20 on an interval scale, where higher scores indicate greater creativity. The results are shown in Table 2. Using the 0.05 alpha level, are introverts more creative than extroverts? Use all of the steps of hypothesis testing. extrovert introvert 8 18 7 17 11 10 3 14 5 16 8 15 7 19 4 12

Base on the same given data uploaded in module 4, will you conclude that the number of bathroom of houses is a significant factor for house price? I your answer is affirmative, you need to explain how the number of bathroom influences the house price, using a post hoc procedure. (Please treat number of bathrooms as a categorical variable in this analysis) Base on the same given data, conduct an analysis for the variable sale price to see if sale price is influenced by living area. Summarize your finding including all regular steps for your method. Also, will you conclude that larger house corresponding to higher price (justify)?
