Q. 4 - Elementary Statistics

Question

The area under a density curve that lies between 5 and 6 is $0.728$. What percentage of all possible observations of the variable are cither less than 5 or greater than 6 ?

Step-by-Step Solution

Answer

The percentage of all observations of the variable is $0.272$.

Step 1: Given Information

The area under a density curve that lies between 5 and 6 is $0.728$. What percentage of all possible observations of the variable.

Step 2: Explanation

One minus area less than $5$or more than $6$equals the area under the density between$5$ and $6$.

The necessary area is

 $=1-0.728$

$=0.272$

Hence, the percentage of all observations of the variable is $0.272.$
