Definition 6.4. A continuous random variable X is said to have a chi-square distribution with r degrees of freedom if its probability density function is of the form 1 if 0 0. If X has a chi-square distribution, then we denote it by writing X ~ x²(r). 17. If the random variable Y has a chi-square distribution with 54 degrees of freedom, then what is the approximate 84th percentile of Y?

Which of the following statements about the inclusion of dummy variables in econometric equations is false? O a. The dependent variable on the left side of an equation can be a dummy variable O b. An equation can have both a slope dummy and an intercept dummy on the right hand side O c.If there is a dummy variable as the dependent variable on the left side of an equation, intercept dummy cannot be placed as the explanatory variable on the right side; only a slope dummy can be placed on the right side O d. If there is a dummy variable as the dependent variable on the left side of an equation, both the intercept and the slope dummy can be placed as the explanatory variable on the right side
