Question

Students measured their heights. The dot plots display the data.

Box plot female versus male

Based on the data, is there a significant difference in the population heights?


1)Yes, because the difference in means ÷ by the larger MAD is greater than 2 MADs.


2)No, because the difference in means ÷ by the larger MAD is less than 2 MADs.


3)Yes, because the difference in means ÷ by the larger MAD is less than 2 MADs.


4)No, because the difference in means ÷ by the larger MAD is greater than 2 MADs.

Answer 1

1)Yes, because the difference in means ÷ by the larger MAD is greater than 2 MADs.

Step-step explanation:

Difference in means:

70.5 - 64.1

= 6.4

Larger MAD:

1.7

6.4/1.7 = 3.764705882 > 1.7
