The management of your team wants to compare the team with the assigned team (the Bulls in 1996-1998). They claim that the skill level of your team in 2013-2015 is the same as the skill level of the Bulls in 1996 to 1998. In other words, the mean relative skill level of your team in 2013 to 2015 is the same as the mean relative skill level of the Bulls in 1996-1998. Test this claim using a 1% level of significance. Assume that the population standard deviation is unknown. Make the following edits to the code block below: 1. Replace ??DATAFRAME_ASSIGNED_TEAM?? with the name of assigned team's dataframe. See Step 1 for the name of assigned team's dataframe. 2. Replace ??DATAFRAME_YOUR_TEAM?? with the name of your team's dataframe. See Step 2 for the name of your team's dataframe. 3. Replace ??RELATIVE_SKILL?? with the name of the variable for relative skill. See the table included in Project Two instructions above to pick the variable name. Enclose this variable in single quotes. For example, if the variable name is var2 then replace ??RELATIVE_SKILL?? with 'var2'.

Question 2: An organization depends on a number of different types of persons for its successful operation. The organization is interested in the following attributes for all these persons: SSN, Name, Address, and Telephone. A person may have multiple telephone numbers. Three types of persons are of greatest interest: employees, volunteers, and donors. Employees only have a Date Hired attribute, and volunteers only have a Skill attribute. Donors only have a relationship (named Donators) with an item that has number and name. a donor must have donated one or more items, and an item may have no donors, or one donor. There are persons other than employees, volunteers, and donors who are of interest to the organization, so that a person need not belong to any of these three groups. On the other hand, at a given time a person may belong to two or more of these groups (for example, employees and donors). Draw an EER diagram based on the requirement above. Note: Consider the Enhanced…
The Frequentist approach looks at Question 17 options: the long-term relative frequency of events occurring both single events occurring and the long-term relative frequency of events occurring a single event occurring neither single events occurring nor the long-term relative frequency of events occurring For data that is approximately normally distributed, any observation more than 1 standard deviation away from the mean is an outlier. Question 26 options: True False
Suppose that you want to increase all three of the resource availabilities in the product mix model simultaneously by the same percentage. You want this percentage to vary from 225% to 50% in increments of 5%. Modify the spreadsheet model slightly so that this sensitivity analysis can be performed with a one- way SolverTable, using the percentage change as the single input. Keep track of the computers produced in row 21, the hours used in the range B26:B28, and the total profit. Discuss the results.
Develop an entity-relationship model for the following scenario. A piano manufacturer wants to keep track of all the pianos it makes individually. Each piano has an identifying serial number and a manufacturing completion date. The manufacturer has piano technicians who are responsible for inspecting the instruments before they are shipped to the customers. Each piano is inspected by one or more technicians (identified by their employee number). For each separate inspection, the company needs to record its date and a quality evaluation grade.
You are building a classification model to predict whether a firm will go bankrupt within the next 5 years. When you collect the data, you find that the number of instances of firms that went bankrupt is smaller than the number of cases of firms that did not go bankrupt. Specifically, only 7% of the firms went bankrupt, while the rest did not go bankrupt. Once you build the classification model, you need to compare performance against a baseline. Which of the following would be an appropriate baseline? O Always predicting that the firm does not go bankrupt O Making a prediction that a firm goes bankrupt with 7% probability O Always predicting that the firm goes bankrupt Making a prediction from the set (bankrupt, not bankrupt) with equal probability
Q1. Define the following terms: accuracy, false positive rate, specificity, recall and f1-score. Give their formula with regards to a confusion matrix like the one below. Given the following confusion matrix, calculate all of the above parameters. IF you cannot calculate any, please provide what more information you need to calculate that particular parameter| Predicted: Predicted: n=165 NO YES Actual: NO 50 10 Actual: YES 100
"Given the following business scenario, create a Crow’s Foot ERD using a specialization hierarchy if appropriate.Tiny Hospital keeps information on patients and hospital rooms. The system assigns each patient a patient ID number. In addition, the patient’s name and date of birth are recorded. Some patients are resident patients who spend at least one night in the hospital, and others are outpatients who are treated and released. Resident patients are assigned to a room. Each room is identified by a room number. The system also stores the room type (private or semiprivate) and room fee. Over time, each room will have many patients. Each resident patient will stay in only one room. Every room must have had a patient, and every resident patient must have a room"
Given the following business scenario, create a Crow’s Foot ERD using a specialization hierarchy if appropriate. Eastern Sales Company keeps information on employees and the departments that they work in. For each department, the department name, internal mail box number, and office phone extension are kept. A department can have many assigned employees, and each employee is assigned to only one department. Employees can be salaried employees, hourly employees, or contract employees. All employees are assigned an employee number. This is kept along with the employee’s name and address. For hourly employees, hourly wage and target weekly work hours are stored (e.g. the company may target 40 hours/week for some, 32 hours/week for others, and 20 hours/week for others). Some salaried employees are salespeople that can earn a commission in addition to their base salary. For all salaried employees, the yearly salary amount is recorded in the system. For salespeople, their…
The validation-set approach allows one to evaluate the performance of different models during model selection. (i) After applying a validation-set approach, the validation errors of two models f1 and f2 are found to be respectively E1 = 10 and E2 = 12. How would you use this result to inform your selection
To see how accurate your trend line is, right click the line and select Describe Trend Line. Tableau will show you the regression equation and the p-value for its overall significance. Group of answer choices True False
Assume an attribute (feature) has a normal distribution in a dataset. Assume the standard deviation is S and the mean is M. Typically: Group of answer choices, multiple choice: Then the outliers usually lie below -3*M or above +3*M Then the outliers usually lie above -3*S or below +3*S Then the outliers usually lie below -3*S or above +3*S Then the outliers usually lie above -3*M or below +3*M
A team averaging 106 points is likely to do very well during the regular season. The coach of your team has hypothesized that your team scored at an average of less than 106 points in the years 2013-2015. Test this claim at a 1% level of significance. For this test, assume that the population standard deviation for relative skill level is unknown. Use the information in the picture to write a block of code. Here is some information that will help you write this code block. Reach out to your instructor if you need help. The dataframe for your team is called your_team_df. The variable 'pts' represents the points scored by your team. Calculate and print the mean points scored by your team during the years you picked. Identify the mean score under the null hypothesis. You only have to identify this value and do not have to print it. (Hint: this is given in the problem statement) Assuming that the population standard deviation is unknown, use Python methods to carry out the hypothesis…
