1. 

Describe the results of this experiment. Plant 1 and plant 2 results in this experiment were similar in height. Plant one was faster in growing. Plant 2 was the slowest on growing. Standard Deviation can be used for the results which it shows the highest number for growing height was in week 8 with 10 centimeters starting at 0 centimeters in week 1.

2. If you wanted to compare the data in Activity 1 to the data in Activity 2, how might you do this?  By using a plot scattering and using a regression line to be able to compare the information from plant 1 and 2. Also using Statistically standard deviation shows the results and there are difference within the data, and it is marked differently to make it easier to understand.

1. Based on the corrected trend lines, which wheat plant grew fastest?  Looking at the graph it seems that because of better slope plant 1 grew much faster. Since it had and big slope it grew taller in height based on the increased of slope in weeks compared with plant 2-3. 2. Why do you set the y-intercept to 0?  The Y-intercept to 0 due the fact on week 0 there is no grow yet is the start of the experiment so it should be measured at 0cm. from 0 the graph lines equation shows increase more than 0 with the lines corrected we should be able to predict the wheat plant experiment length in order to come up with the solution on which plant grew taller and faster.
