Answer 1

Answer:

4.3

Step-by-step explanation:

LET SAMPLE OF 6 NUMBERS BE=a,b,c,d,e,f

mean=of 6 observation=4.2

 therefore=a+b+c+d+e+f/6=4.2

                so    a+b+c+d+e+f=4.2*6=25.2................(1)

          if 4.9 is included

       there fore

  mean=a+b+c+d+e+f+4.9/7

             25.2+4.9/1                                      (from  1)

       mean=30.1/7=4.3
