- SITUATION For Valentine's Day 5 students of a certain school came up with a project to hand out gingerbread cookies that they would bake for those single on Valentine's Day. Upon brainstorming, three of them namely Aries, Kim and Chen suggested to design a human-shaped bread (normal design), the other two Anton and Jade suggested a robot-shaped cookie design. In compromise with the two design ideas, they have come up with the hybrid sketch below. Each of them took up the task of calculating the area of the gingerbread. Solve for the ff: 1. Aries's task is the area 1 (refer to figure 1.2) which are the leg of the bread. 2. Kim's task is the area 2 (refer to figure 1.2) which is the body of the bread. 3. Chen's task is the area 3 (refer to figure 1.2) which are the arm of the bread. 4. Anton's task is the area 4 (refer to figure1.2) which is the box head of the bread. 5. Jade's task is the area 5 (refer to figure 1.2) which are the antennae and the semicircular ears of the bread.…Learning psychologist Edward Tolman wanted to determine if mice learned a maze through trial and error or if the developed a “cognitive map” of the maze. Tolman placed a rat in the center of a circular space with 4 alternative corridors. If the rats were truly “guessing” a path, they should try each corridor an equal number of times. However, if the rats were developing a cognitive map, they should go down the far-right corridor more frequently than the others and go directly to the cheese. Original Right Observed 8 12 Expected 16 16 . a.What are the null and alternative hypotheses? b.Perform the analysis manually or using Excel or r. c.Why is a Chi-Square called goodness of fit rather than a hypothesis test d.What did Tolman find?Describe a strategy for solving an SAS triangle.
- we are going to use linear programming to develop a simple machinelearning algorithm to help us classify data points. Training data and Test data.Each of the 20 data points in the training data consists of 2 sensor readings x1, x2 whichare real numbers corresponding to the readout of two sensors during an event and a classi-cation y which is either 0 or 1, 0 indicates the event corresponding to the sensor data wasdetermined to not be a gravitational wave and a 1 indicates the event was determined tobe a gravitational wave. Thus, a typical line in the le looks something like:0.0 78.1 60.6Which indicates the 2 sensors had readings 78.1, 60.6 respectively, and the 0.0 indicatesno gravitational wave was observed. The test data consists again of sensor readings xi but with no classication y provided.Your job is to use the training data to develop a model that can take in sensor data andpredict the classication (again, 0 or 1). You will then run your model on the 20 points inthe test…Elephants and hippos We removed humans from thescatterplot in Exercise 31 because our species was anoutlier in life expectancy. The resulting scatterplot showstwo points that now may be of concern. The point in theupper right corner of this scatterplot is for elephants, andthe other point at the far right is for hippos.a) By removing one of these points, we could makethe association appear to be stronger. Which point?Explain.b) Would the slope of the line increase or decrease?c) Should we just keep removing animals to increase thestrength of the model?
