Question

Which one of the following statements is True?

The Odds against A equals 1 – Odds in favor of A.
For a mound shaped distribution if the skew is positive then the mean is greater than the median.
P(n, r) = C(n, r) / r!
The probability of an event equals the number of favorable outcomes divided by the number of unfavorable outcomes.
A Bimodal distribution is symmetric.

Expert Solution

Step 1

Statement 1 : False

$O d d s i n f a v o r o f A = \frac{F a v o r a b l e o u t c o m e s}{U n f a v o r a b l e o u t c o m e s}$

$O d d s i n a g a i n s t A = \frac{U n f a v o r a b l e o u t c o m e s}{F a v o r a b l e o u t c o m e s}$

Statement 2 : True.

For positive skewed distribution : Mode < median < mean
For symmetric distribution : Mode = mean = Median
For negative skewed distribution : Mode > median > mean
