1. There were 80 plants in a study. 40 were given Fertilizer A and 40 were given #1 Score Fertilizer B. The plants in Group A grew to an average of 27.2 inches and the plants in Group B grew to an average of 24.2 inches. To determine if this difference is significant, the groups were rerandomized 10 times. The rerandomizations were rounded to the nearest whole number and are shown on the line plot below. ХХХХ Х N + XX 0 1 3 4 5 A) State whether the difference in the means of the two groups is significant based on the line plot (3 points) I B) Explain your answer (6 points).​

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
