Question

dissolved oxygen data:
calculate the average dissolve oxygen for each site and input it into the appropriate locations on the data tables!
test site 1
test site 6

test site 1 table:
sample number | dissolved oxygen (mg/l)
1 | 8
2 | 8
3 | 11
4 | 8
5 | 9
6 | 10
average |

test site 6 table:
sample number | dissolved oxygen (mg/l)
1 | 2
2 | 4
3 | 2
4 | 4
5 | 3
6 | 3
average |

Explanation:

Test Site 1

Step1: Sum the dissolved oxygen values

The values for Test Site 1 are \( 8, 8, 11, 8, 9, 10 \). The sum is \( 8 + 8 + 11 + 8 + 9 + 10 = 54 \).

Step2: Calculate the average

There are 6 samples. The average is \( \frac{54}{6} = 9 \).

Test Site 6

Step1: Sum the dissolved oxygen values

The values for Test Site 6 are \( 2, 4, 2, 4, 3, 3 \). The sum is \( 2 + 4 + 2 + 4 + 3 + 3 = 18 \).

Step2: Calculate the average

There are 6 samples. The average is \( \frac{18}{6} = 3 \).

Answer:

Test Site 1 Average: \( 9 \) mg/L
Test Site 6 Average: \( 3 \) mg/L
