What is the sst for the data set (1,4), (2,,11)?

26

Step-by-step explanation:

First Data: (4 - 7)^2

Second data: (6 - 7)^2

Third Data: (11 - 7)^2

So the SST is (4 - 7)^2 + (6- 7)^2 + (11 - 7)^2 = 9 + 1 + 16 = 26

Hope this helps! :)

26

Step-by-step explanation:

SST = ∑ ( y − ȳ ) ² (ȳ = pronounced y bar is the mean of y values)

ȳ = (4+6+11)/3 = 21/3 = 7

∑ ( y − ȳ ) ² =  ( 4 − 7 ) ² +  ( 6 − 7 ) ² +  ( 11 − 7 ) ²

=  (  − 3 ) ² +  (  - 1 ) ² +  ( 4 ) ²

= 9 + 1 + 16

= 26

for b its (t) and c its (d)
