If the heights of a group of people are normally distributed, the average height is 67 inches, and the standard deviation of the heights is 2.5 inches, then what proportion of people in the group are shorter than five feet? (Give the proportion rounded to four decimal places.)

  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.
