In a useful simple linear regression analysis, the independent variable…
is used to predict other independent variables
is used to predict the dependent variable
has no effect on the dependent variable
is the variable that is being predicted using the regression equation
According to an article, one may be able to predict an individual's level of support for ecology based on demographic and ideological characteristics. The multiple
regression model proposed by the authors was the following.
y = 3.60-.01x₁+.01.₂-.07x3+.12x4+.02xs-.04x6-01-.04.xg-.02.xg+c
The variables are defined as follows.
y = ecology score (higher values indicate a greater concern for ecology)
X₁ = age times 10
x₂ = income (in thousands of dollars)
x3 = gender (1 = male, 0 = female)
X4 = race (1 = white, 0 = nonwhite)
X5 = education (in years)
x6 = ideology (4 = conservative, 3 = right of center, 2 = middle of the road, 1 = left of center, and 0 = liberal)
X7 = social class (4 = upper, 3 = upper middle, 2 = middle, 1 = lower middle, 0 = lower)
xg = postmaterialist (1 if postmaterialist, 0 otherwise)
x9 = materialist (1 if materialist, 0 otherwise)
(a) Suppose you knew a person with the following characteristics: a 30 year old, white female with a college degree (20 years of…
A study was conducted to see if a person's income will affect their well-being. We want to create a model with Y = well-being index, and X =
income in $1,000. The dependent variable in this study is:
Income in $1,000
Well-being index
Neither

- Linear regression is a highly effective data analysis method that accurately estimates the value of unknown data using related and known data. This is achieved using a linear equation that accurately models the quantitative relationship between the dependent (unknown) and independent (known) variables. In other words, by looking at how one variable affects another, this method can accurately forecast the value of the dependent variable. It involves choosing the variable to forecast and using another variable to make informed predictions about its value. In experiments, the independent variable is the cause, and its value remains constant while other variables have been modified. On the other hand, the dependent variable is the effect, and changes influence its value in the independent variable. As I began my business, I struggled with determining the appropriate pricing for my products. It was important that the prices were reasonable while allowing for a profit. The pricing had to…arrow_forwardResearch indicates that the weight of cows can be predicted by using measurements of heart girth (i.e. width). A linear regression equation can be used to calculate changes in weight as heart girth changes; so here heart girth is the independent variable x (measured in centimetres), and weight is the dependent variable y (measured in kilograms). A sample of six cows is taken; the linear regression equation is then calculated, and it is found to be y = -974.05 + 7.53x. (i) What is the slope of the above linear regression equation? Interpret its meaning in the context given here. (ii) The correlation coefficient for the data collected above is r= 0.973. What does this tell us about the relationship between x and y?arrow_forwardWe have data on Lung Capacity of persons and we wish to build a multiple linear regression model that predicts Lung Capacity based on the predictors Age and Smoking Status.

The expected lung capacity of a smoker is expected to be 0.648588 lower than that of a non-smoker. B. The predictor variables Age and Smoker both contribute significantly to the model. C. For every one year that a person gets older, the lung capacity is expected to increase by 0.555396 units, holding smoker status constant. D. For every one unit increase in smoker status, lung capacity is expected to decrease by 0.648588 units, holding age constant.arrow_forward
- According to an article, one may be able to predict an individual's level of support for ecology based on demographic and ideological characteristics.
