Consider the means of the samples shown in the table. which value is least likely to be the mean of the population from which the samples were taken? sample//sample mean .2 2 .1 3 .9 4 .2 .0 6 .3 7 .4 a.12.2 b.15.3 c.16.4 d.17.5

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
