Thirty children and forty-five adults were surveyed to determine if children watch, on average, the same amount of television as adults per day. the averages from the study were 3.4 and 2.7 hours per day, respectively. the standard deviations from the study were 2.3 and 1.4 hours per day, respectively. the hypothesis test to use is

the answer to this question is yes

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
