<span>The sum of 324, 435, and 546 is 1305. If this number were to be expressed by the base of 7, we would need to figure out what value of exponent would satisfy the requirement. This can be done by setting up an equation where 7 to the power of x must equal 1305. Using logarithms, one can solve for x and find it to be 3.6866853. Thus the sum of the aforementioned numbers, expressed in by the base of 7, is 7^3.6866853.</span>
        
             
        
        
        
Answer:
A) No
B) No
C) Yes
Step-by-step explanation:
A)  2 out of three observations is equal to
2/3  = 0.67    or  67 %
We know tha the interval 
[μ  -  σ/2 ,  μ + σ/2]  is approximately 68.3 % of the values
Therefore 2 out of 3 would not fall in that interval
B)
4 out of  5   is  4/5    = 0,8     or 80 %  If we  examine the interval
[μ  -  σ ,  μ + σ ]   which is approximately 95. Then value 4/5  ( 0,8)
Therefore 0,8 is out of the interval
C) 19/20 = 0,95     or 95 % is almost exact the value for the interval
[μ  -  1.5σ ,  μ + 1.5σ ]  That value is inside  μ - 2σ , μ + 2
