A real estate agent wanted to find the relationship between sale price of houses and the size of the house. She collected data on two variables recorded in the following table for 15 houses in Seattle. The two variables are PRICE= Sale price of houses in thousands of dollars SIZE= Area of the entire house in square feet. PRICE 455 278 463 327 505 264 445 346 487 289 434 411 223 323 488 250 225 290 180 320 240 270 205 285 240 260 230 170 230 298 SIZE a) Using MICROSOFT EXCEL- run the above regression and copy the output into your assignment word document from which you can write down the least square regression line. Write down the least square regression line from that specific output. USE THE NAME OF VARIABLES WHEN YOU WRITE THE EQUATION. b) Interpret the slope and constant term with proper UNITS assigned. c) Comment on the explanatory power of the regression model from the required output. Copy that specific output into your assignment word document.

Laila wants to create a data display to clearly show the median salary, the highest salary. and the lowest salary of the 685 employees at her company. She is trying to decide whether she should create a dot plot, a box plot, or a histogram of the salaries. A sample of the data is shown below. $25,745; $26,512; $27,322; $27.750; $29,820; $32,500; $35,448; $52,020; $63,485: $87,167 Which graph should Laila choose? Explain your reasoning by completing the sentences.Click the arrows to choose an answer from each menu. A dot plot Choose... option 1 would display the median, minimum and maximum clearly option 2. would not work well because there are too many different values  option 3 cannot be used to determaine the median  A box plot Choose... option 1 would display the median, minimum and maximum clearly option 2. might not show the minimum or the maximum  option 3 cannot be used to determaine the median  A histogram Choose... option 1 would display the median, minimum and maximum clearly…

QDES.B A study was undertaken to see how accurate food labeling for calories on food that is considered "reduced calorie".  The group measured the amount of calories for each item of food and then found the percent difference between measured and labeled food. The group also looked at food that was nationally advertised, regionally distributed, or locally prepared.  The data is in the following table ("Calories datafile," 2013).  Table:  Percent Differences Between Measured and Labeled Food National Advertised Regionally Distributed Locally Prepared 2 41 15 -28 46 60 -6 2 250 8 25 145 6 39 6 -1 16.5 80 10 17 95 13 28 3 15 -3   -4 14   -4 34   -18 42   10     5     3     -7     3     -0.5     -10     6       Do the data indicate that at least two of the mean percent differences between the three groups are different?…

4.3) •VA report from Texas Transportation Institute (Texas A&M University System 2005) on Congestion Re- duction Strategies looked into the extra travel time (due to traffic congestion) for commute travel per traveler per year in hours for different urban areas. Below are the data for urban areas that had a population of over 3 million for the year 2002. Extra Hours per Traveler per Year Urban Area Los Angeles San Francisco 98 75 Washington DC Atlanta 66 64 Houston 65 Dallas, Fort Worth Chicago Detroit 61 55 54 Miami 48 Boston 53 New York 50 Phoenix 49 Philadelphia 40 4. Compute the mean and median values for extra travel hours. Based on the values of the mean and median, is the distribution of extra travel hours likely to be approximately symmetric, positively skewed, or negatively skewed?
