The following data was collected to explore how the number of square feet in a house, the number of bedrooms, and the age of the house affect the selling price of thehouse. The dependent variable is the selling price of the house, the first independent variable (x1) is the square footage, the second independent variable (x2) is thenumber of bedrooms, and the third independent variable (x3) is the age of the house.Effects on Selling Price of HousesSquare FeetNumber of Bedrooms Age Selling Price27564143103002721412291500266648281100210247265600188037237500182936184600159934160800142233132600119933130500Step 1 of 2: Find the p-value for the regression equation that fits the given data.

A commercial airline is analyzing the price scale for round trip flights between New York and Pennsylvania. The sooner the c buys the ticket, the cheaper the ticket price is. The sales manager collected information for the last year on how many cust bought their tickets at each price: Ticket Price (in dollars) # of Customers (in thousands) 5 15 23 27 20 89 125 135 150 178 198 10 What is the coefficient of correlation between the ticket price and the number of customers purchasing at that price? Answer:
Suppose you run a regression with quantity as your dependent variable and advertising as one of your independent variables. The p-value on advertising is .08. The marketing team is arguing that their advertising efforts are impacting sales, but the finance/economics department is arguing that there isn't evidence that the advertising is impacting sales. What side would you take and why?

xt:Bong-Cha is deciding what to do during the 30-minute break between her college classes. One rule she could follow is, "Choose the activity with the highest value" (A). Another rule she could follow is, "Choose the activity with the lowest opportunity cost" (B). Do you think Bong-Cha's choice if she follows rule (A) will be the same as the choice she would make if she followed rule (B)? [another way to think about it, "Is rule (A) identical to rule (B) in a sense that they would both induce the same choice?"].

← Café Michigan's manager, Gary Stark, suspects that demand for mocha latte coffees depends on the price being charged. Based on historical observations, Gary has gathered the following data, which show the numbers of these coffees sold over six different price values: Price $2.50 $3.50 $1.90 $4.20 $3.20 $4.10 Number Sold 760 515 980 250 320 490 D Using simple linear regression and given that the price per cup is $1.75, the forecasted demand for mocha latte coffees will be 1862.8 cups (enter your response rounded to one decimal place). 88
Use a software of your own choice to calculate the daily log prices (lp) and daily log returns (Ir) i. Examine the descriptive statistics of both lp and Ir. What do you conclude about the distributions of lp and Ir? Is lp normally distributed? Is Ir normally distributed? Obtain the correlograms, and examine the autocorrelations and partial autocorrelations for both lp and Ir. What do you conclude about the behaviour of lp and Ir? Are they stationary/non-stationary? ii. iii. Are your conclusions about stationary/non-stationary of lp and lr confirmed by appropriate unit root tests?
