Question

if the data in the table were entered into a regression calculator to produce a scatterplot and trend line, which window size would display all the points? x y 2 5 5 16 6 20 10 29 12 36 17 53 0 less-than-or-equal-to x less-than-or-equal-to 20; 0 less-than-or-equal-to y less-than-or-equal-to 50 0 less-than-or-equal-to x less-than-or-equal-to 20; 0 less-than-or-equal-to y less-than-or-equal-to 60 0 less-than-or-equal-to x less-than-or-equal-to 50; 0 less-than-or-equal-to y less-than-or-equal-to 20 0 less-than-or-equal-to x less-than-or-equal-to 60; 0 less-than-or-equal-to y less-than-or-equal-to 20

Answer 1

Option: B is the correct answer.

The window size that display all the points are:

0 ≤x ≤ 20 ; 0 ≤ y ≤ 60

Explanation:

We are given a table of values as:

x y

2 5

5 16

6 20

10 29

12 36

17 53

Hence, all the x-values lie in the interval:

0 ≤ x ≤ 20

Similarly, we could observe that the minimum value attained by y is 5 and maximum value attained by y is 53.

Hence, all the y-values lie in the interval:

0 ≤ y ≤ 60

Answer 2

0 less-than-or-equal-to x less-than-or-equal-to 20;

0 less-than-or-equal-to y less-than-or-equal-to 60

Explanation:

The range in values of x is from 2 to 17, so a suitable window would be 0 to 20.

The range in values of y is from 5 to 53, so a suitable window would be 0 to 60.

0 ≤ x ≤ 20

0 ≤ y ≤ 60
