TRUE/FALSE. Write \'T\' if the statement is true and \'F\' if the statement is f

Question

TRUE/FALSE. Write 'T' if the statement is true and 'F' if the statement is false.

30.If two variables have a correlation coefficient equal to -0.60 from a sample size of 5, we can conclude that the population correlation coefficient is less than zero using = 0.05.

31.The line that best fits the ordered pairs using the least squares method is called the residual line.   

32.Given a regression equation of y = 15.6 - 3.8x, a one-unit increase in the independent variable

would result in an average increase of 3.8 for the dependent variable.

MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question.

33.The formula for the equation describing a straight line is y = b0 + b1x. The value for b0 in this equation represents the                    .

A.y-intercept of the straight line B) slope of the straight line   C) predicted value of y given a value of x                     D) independent variable

Explanation / Answer

30) F from sample size of 5 we cant predict the population parameter.

31)T residual line best fit in OLS regresson

32)F one-unit increase in the independent variablewould result in an average decrease of 3.8 for the dependent variable.

33) intercept of the line
