In regression analysis, which of the following causal relationships are possible? a. X causes Y to vary b. Y causes X to vary c. Other variables cause both X and Y to vary d. All of these options

A. X causes Y to vary

Step-by-step explanation:

Regression analysis estimates the relationship between a dependent variable and one or more independent variables. Examples are linear regression, logistic regression, etc. Regression analysis can be used for prediction, forecasting or classification.

In regression analysis, the independent variables, called the inputs, are regarded as causes of the dependent variables.

The variation in the input x will lead to a variation in the output, Y

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
