Question

c. the fish and wildlife agency measured the size of pacific salmon for 1 year and recorded the average weight for each species.
chart:

• salmon species: king, sockeye, silver, chum, humpback
• average weight (lbs): 15, 8, 12, 15, 5

Explanation:

Step1: Sum the weights

We add up all the average weights: \(15 + 8 + 12 + 15 + 5\)
First, \(15+8 = 23\), then \(23 + 12 = 35\), then \(35+15 = 50\), then \(50 + 5 = 55\)

Step2: Divide by the number of species

There are 5 species. So we calculate the mean: \(\frac{55}{5}\)
\(55\div5 = 11\)

Answer:

The average weight for each salmon species is 11 lbs.
