  Frequency
  Mon 25
  Tue 22
  Wed 19
  Thu 18
  Fri 16
   Total 100
 
  Based on this information how many degrees for freedom are involved in this goodness of fit test?
  A) 99
  B) 100
  C) 4
  D) 5

Q. 2

To describe variable credit status that has three levels: Excellent, Good, and Poor, we need to use two different dummy variables.
 
  Indicate whether the statement is true or false

Q. 3

In a simple regression model, if the regression model is deemed to be statistically significant, it means that the regression slope coefficient is significantly greater than zero.
 
  Indicate whether the statement is true or false

Q. 4

Which of the following statements is true in the context of a chi-square goodness-of-fit test?
 
  A) The degrees of freedom for determining the critical value will be the number of categories minus 1.
  B) The critical value will come from the standard normal table if the sample size exceeds 30.
  C) The null hypothesis will be rejected for a small value of the test statistic.
  D) A very large test statistic will result in the null not being rejected.

Q. 5

If a time series involves monthly data there will be a total of 12 seasonal indexes.
 
  Indicate whether the statement is true or false

Q. 6

If the correlation between the dependent variable and the independent variable is negative, the standard error of the regression slope coefficient in a simple linear regression model will also be negative.
 
  Indicate whether the statement is true or false
