An experiment was run to determine whether four specific firingtemperatures affect the density of a certain type of brick. Acompletely randomize experiment led to the following data :

Temperature Density
100 21.8 21.9 21.7 21.6 21.7
125 21.7 21.4 21.5 21.4
150 21.9 21.8 21.8 21.6 21.5
175 21.9 21.7 21.8 21.4
Does the firing temperature affect the density of the bricks ?Use α = 0.05

There is not enough evidence to know if the firing temperature affects the density of the bricks

Step-by-step explanation:

My explanation refused to be posted here, so i have attached it below.

Start from the last image to the first one

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

1 is c

2 is a

3 is a
