A few rows from a dataset are shown below. Assume that the house_price represents the price in dollars. (Ignore the fact that these prices are unrealistic in today’s market) | square_feet| house_price|property_type |location_grade | |———–:|———–:|:————-|:————–| | 2282| 2604|Townhome |A | | 1624| 1103|Townhome |C | | 2189| 2670|Condo |C | | 1737| 1747|House |C | | 1905| 2428|House |A | | 1549| 1456|Townhome |A | For the above, I built a model with house_price as the response variable and property_type and square_feet as the explanatory variables. I then computed different variances and standard deviations as shown below. The column names are self-explanatory. | model_var| house_price_sd| residual_sd| residual_var| model_sd| house_price_var| |———:|————–:|———–:|————:|——–:|—————:| | 434547.5| 877.2213| 578.7656| 334969.7| 659.2022| 769517.1|   Based on the above, how much of the variability in the response variable does the model explain? Enter a number between 0 and 1 correct to two decimal places.

When we increase the confidence level (say from 95% to 99%) the width of the confidence interval

Which three of the following do we generally calculate to determine the explanatory power of a model (and therefore also how much the model leaves unexplained)? 

The first figure below shows the distribution of annual incomes of people in some country in the form of a continuous probability density function.  The shaded region corresponds to the area under the curve for x values above $24,960 (average income). A label shows the numeric value of this area.The second figure shows the same probability density function, but with the area under the curve for x-values above $15,700 shaded. Using these figures, what is the probability that someone earns between 15700 and 24960? Write in a number between 0 and 1 correct to two decimal places?

Design and implement a Java application that creates a simple visual representation of data frequencies. The program should prompt the user to enter an arbitrary number of integers, each in the range 1 to 100 inclusive. After all values are entered, the program should display a chart showing how many of the entered values fall into each of the following ranges: 1 to 25 26 to 50 51 to 75 76 to 100 The chart should use one asterisk (*) per value in each range to represent the frequency visually. Sample test case: ———————————————————————– Input: Enter values (1 to 100). Type -1 to stop:12436788257639-1 Output:   1 –   25 | **26 –   50 | **51 –   75 | *76 – 100 | ** ———————————————————————– Input: Enter values (1 to 100). Type -1 to stop:120Invalid input. Please enter a number between 1 and 100.45-12Invalid input. Please enter a number between 1 and 100.8025-1 Output:   1 –   25  | *26 –   50  | *51 –   75  |76 – 100  | * As always, take a moment to think through the problem before jumping into code. Write down the steps you would take, consider how methods can help you abstract parts of the solution (e.g., ‘Assume method X gives me this result—what next?’), and focus on identifying what you already know versus what you still need to figure out. Clear thinking leads to clearer code!
