Quantitative Analysis II
, The F distribution's curve is positively skewed. - CORRECT ANSWERS-True
The test statistic used in ANOVA is Student's t. - CORRECT ANSWERS-False
There is one, unique F distribution for a F-statistic with 29 degrees of freedom in the
numerator and 28 degrees of freedom in the denominator - CORRECT ANSWERS-True
One characteristic of the F distribution is that F cannot be negative. - CORRECT
ANSWERS-True
One characteristic of the F distribution is that the computed F can only range between -
1 and +1. - CORRECT ANSWERS-False
The shape of the F distribution is determined by the degrees of freedom for the F-
statistic, one for the numerator and one for the denominator. - CORRECT ANSWERS-
True
Unlike Student's t distribution, there is only one F distribution. - CORRECT ANSWERS-
False
Like Student's t distribution, a change in the degrees of freedom causes a change in the
shape of the F distribution. - CORRECT ANSWERS-True
If the computed value of F is 0.99 and the critical value is 3.89, we would not reject the
null hypothesis. - CORRECT ANSWERS-True
To employ ANOVA, the populations being studied must be approximately normally
distributed. - CORRECT ANSWERS-True
To employ ANOVA, the populations should have approximately equal standard
deviations. - CORRECT ANSWERS-True
In an ANOVA table, k represents the total number of sample observations and n
represents the total number of treatments. - CORRECT ANSWERS-False
The alternate hypothesis for ANOVA states that not all the means are equal. -
CORRECT ANSWERS-True
For an ANOVA test, rejection of the null hypothesis does not identify which treatment
means differ significantly. - CORRECT ANSWERS-True
If the computed value of F is 4.01 and the critical value is 2.67, we would conclude that
all the population means are equal. - CORRECT ANSWERS-False
If the computed value of F is 11.1 and the 0.05 level is used, we would assume that a
mistake in arithmetic has been made. - CORRECT ANSWERS-False
