environmental change: add pollutant (nitrogen from fertilizer)
quantitative data: number of living shrimp

day	control group (count # alive in 4 boxes then find average)	x150	experimental group (count # alive in 4 boxes then find average)	x150
2	19, 15, 17, 18, avg		12, 9, 8, 6, avg
3	23, 19, 19, 22, avg		8, 11, 3, 4, avg

Explanation:

Step1: Calculate Control Avg (Day1, pH Drop)

$\frac{16 + 12 + 14 + 15}{4} = \frac{57}{4} = 14.25$

Step2: Calculate Experimental Avg (Day1, pH Drop)

$\frac{14 + 17 + 13 + 15}{4} = \frac{59}{4} = 14.75$

Step3: Calculate Control Avg (Day2, pH Drop)

$\frac{19 + 15 + 17 + 18}{4} = \frac{69}{4} = 17.25$

Step4: Calculate Experimental Avg (Day2, pH Drop)

$\frac{4 + 2 + 3 + 3}{4} = \frac{12}{4} = 3$

Step5: Calculate Control Avg (Day3, pH Drop)

$\frac{23 + 19 + 19 + 22}{4} = \frac{83}{4} = 20.75$

Step6: Calculate Experimental Avg (Day3, pH Drop)

$\frac{0 + 1 + 5 + 2}{4} = \frac{8}{4} = 2$

Step7: Calculate Control Avg (Day1, Nitrogen)

$\frac{16 + 12 + 14 + 15}{4} = 14.25$

Step8: Calculate Experimental Avg (Day1, Nitrogen)

$\frac{14 + 17 + 13 + 15}{4} = 14.75$

Step9: Calculate Control Avg (Day2, Nitrogen)

$\frac{19 + 15 + 17 + 18}{4} = 17.25$

Step10: Calculate Experimental Avg (Day2, Nitrogen)

$\frac{12 + 9 + 8 + 6}{4} = \frac{35}{4} = 8.75$

Step11: Calculate Control Avg (Day3, Nitrogen)

$\frac{23 + 19 + 19 + 22}{4} = 20.75$

Step12: Calculate Experimental Avg (Day3, Nitrogen)

$\frac{8 + 11 + 3 + 4}{4} = \frac{26}{4} = 6.5$

Step13: Scale all averages (×150)

Control (pH Drop, Day1): $14.25 \times 150 = 2137.5$
Experimental (pH Drop, Day1): $14.75 \times 150 = 2212.5$
Control (pH Drop, Day2): $17.25 \times 150 = 2587.5$
Experimental (pH Drop, Day2): $3 \times 150 = 450$
Control (pH Drop, Day3): $20.75 \times 150 = 3112.5$
Experimental (pH Drop, Day3): $2 \times 150 = 300$
Control (Nitrogen, Day1): $14.25 \times 150 = 2137.5$
Experimental (Nitrogen, Day1): $14.75 \times 150 = 2212.5$
Control (Nitrogen, Day2): $17.25 \times 150 = 2587.5$
Experimental (Nitrogen, Day2): $8.75 \times 150 = 1312.5$
Control (Nitrogen, Day3): $20.75 \times 150 = 3112.5$
Experimental (Nitrogen, Day3): $6.5 \times 150 = 975$

Answer:

Decrease pH (Add Acid) Experiment

DAY	Control Group Averages	Control ×150	Experimental Group Averages	Experimental ×150
2	17.25	2587.5	3	450
3	20.75	3112.5	2	300

Add Pollutant (Nitrogen) Experiment

DAY	Control Group Averages	Control ×150	Experimental Group Averages	Experimental ×150
2	17.25	2587.5	8.75	1312.5
3	20.75	3112.5	6.5	975
