Which associations best describe the scatter plot?
i need ! 15 !
select each correct answer.
negative association
nonlinear association
positive association
linear association
scatter plot on a first quadrant coordinate grid. the horizontal axis is labeled time, in years. the vertical axis is labeled number infected. points are plotted at (one, one hundred), (two, ninety), (three, seventy-five), (four, sixty), (five, forty-five), (six, twenty-five), (seven, fifteen), (eight, five), (nine, zero).

answer:   linear and negative association.

step-by-step explanation:

the given points of the scatter plot are,

x         1         2         3           4         5         6           7         8         9

y     100     90       75         60       45       25       15         5         0

since, according to the relation between independent variable (x) and dependent variable (y) there are three types of the scatter plot,

positive correlation: y increases as x increases

negative correlation: y decreases as x increases

none correlation :   if there is no apparent relation between x and y.

also, positive and negative correlation are always linear.

by the above table,

we can say that, with increasing the value of x the value of y is decreasing.

that is,

thus, given scatter plot has negative and linear association.

⇒ first and last option is correct.
