DB1WK2 Answer the following questions and post your answers: 1. In your own words, what is meant by the statement that correlation does not imply causality? 2. Values of r: If you had computed the value of the linear correlation coefficient to be 1.200, what should you conclude?
Construct a histogram in Minitab of your professor’s commute times. Explain the shape of the histogram in detail, what, why, when, how.
Minitab Assignment Number 2 The following data are commute times (in minutes) from your professor’s home to work for 25 consecutive workdays. Key the data in Minitab in C1 and name the column Commute Times. Construct a histogram in Minitab of your professor’s commute times. Your first Minitab assignment walks you through how to create […]

Consider a similar medium but with linear loss for the ω1 wave only. Do any of W, M1, M2, M3 remain constants of motion? Why?
Nonlinear Optics (50 points) The equations of motion describing nonlinear coupling of three plain waves in a lossless χ(2) medium are given in the slowly-varying envelope approximation as (1) (2) (3) where ωj and nj are the angular frequency and refractive index, respectively, of jth wave (j = 1,2,3). K is the effective second-order susceptibility. […]
Determine the coefficient of determination (r2). Determine whether to use this equation for estimating purposes.
VOLUME CHEMICAL You are involved in analyzing the relationship between the cost and the volume of production. You have collected the following inflation‐adjusted data: Table 3.12—Volume Chemical Inflation-Adjusted Data Production Units Costs 700 $61,750 1,450 $64,450 1,500 $66,000 1,750 $69,438 2,100 $73,410 2,150 $75,720 3,050 $79,375 Estimate the cost to produce 2,000 units. Determine the […]
Calculate the coefficient of determination. Determine the regression equation. Is there a positive association between the size of the house and its selling price?
Correlation coefficient 1-A sample of 12 houses that were sold last week in San Juan is selected. Can we conclude that, as the size of the house (reported in thousands of square feet in the table below) increases, so does the sale price. The following table in thousands of square feet), the selling price (reported […]
Determine r and what it means, including determining the strength of the correlation and discussing how you determine the direction of the association between the two variables.

Construct the formula and apply it to real-world situations correctly. Find another formula that you use in your daily life, and explain the meaning behind it.
Understanding Equations Being successful in mathematics requires understanding as opposed to simple memorization. For example, the formula to find the perimeter of a rectangle is P = 2L + 2W (where L is length and W is width). Memorizing the formula could be helpful, but, if we understand that the perimeter is the distance around […]
