Null hypothesis significance testing uses the laws of probability to estimate the likelihood of an outcome by first assuming that

The blank is - only chance factors caused the outcome.

Step-by-step explanation:

Null hypothesis significance testing uses the laws of probability to estimate the likelihood of an outcome by first assuming that - only chance factors caused the outcome.

This kind of testing is a statistical testing where an experimental factor is tested against the hypothesis of no effect based on a given observation.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

all it means is function 3
