Explanation:

Step1: Calculate Control Group Averages (Increase Salinity)

Day 1:

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

Day 2:

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

Day 3:

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

Step2: Calculate Experimental Group Averages (Increase Salinity)

Day 1:

$\frac{23 + 21 + 14 + 16}{4} = \frac{74}{4} = 18.5$

Day 2:

$\frac{22 + 18 + 15 + 19}{4} = \frac{74}{4} = 18.5$

Day 3:

$\frac{24 + 19 + 14 + 14}{4} = \frac{71}{4} = 17.75$

Step3: Calculate Control Group Averages (Decrease Temperature)

Day 1:

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

Day 2:

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

Day 3:

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

Step4: Calculate Experimental Group Averages (Decrease Temperature)

Day 1:

$\frac{11 + 8 + 7 + 5}{4} = \frac{31}{4} = 7.75$

Day 2:

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

Day 3:

$\frac{0 + 3 + 4 + 2}{4} = \frac{9}{4} = 2.25$

Step5: Calculate X150 Values (Multiply avg by 150)

Increase Salinity Control:

Day1: $14.25 \times 150 = 2137.5$
Day2: $17.25 \times 150 = 2587.5$
Day3: $20.75 \times 150 = 3112.5$

Increase Salinity Experimental:

Day1: $18.5 \times 150 = 2775$
Day2: $18.5 \times 150 = 2775$
Day3: $17.75 \times 150 = 2662.5$

Decrease Temperature Control:

Day1: $14.25 \times 150 = 2137.5$
Day2: $17.25 \times 150 = 2587.5$
Day3: $20.75 \times 150 = 3112.5$

Decrease Temperature Experimental:

Day1: $7.75 \times 150 = 1162.5$
Day2: $3 \times 150 = 450$
Day3: $2.25 \times 150 = 337.5$
