The manager can be 95% confident that the true value of the underlying parameters in a regression is not zero if the absolute value of t-statistic is

  • Greater than 2

The lower the standard error,

  • The more confident the manager can be that the parameter estimates reflect the true values

 Suppose the income elasticity for transportation is 1.8. Which of the following is anincorrect statement?

  • Expenditures on transportation will fall less rapidly than income falls
Since most consumers spend very little on salt, a small increase in the price of salt will
  • Not reduce quantity demanded by very much

 If the short-term own price elasticity for transportation is estimated to be -0.6, then long-term own price elasticity is expected to be

  • Less than -0.6

Which of the following is not the important factor that affects the magnitude of the own price elasticity of a good?

  • Supply of the good

The demand for good X is estimated to be QX d = 10, 000 – 4PX + 5PY + 2M + AX, where PX is the price of X, PY is the price of good Y, M is income and AX is the amount of advertising on X. Suppose the present price of good X is $50, PY = $100, M = $25,000, and AX = 1,000 units. Based on this information, good X is

  • A normal good

The demand for good X is estimated to be QX d = 10, 000 – 4PX + 5PY + 2M + AX, where PX is the price of X, PY is the price of good Y, M is income and AX is the amount of advertising on X. Suppose the present price of good X is $50, PY = $100, M = $25,000, and AX = 1,000 units. Based on this information, the income elasticity of good X is
