help will give like. there is no data, everything is in the first image. will give like, im struggling with this part

# Scenario 3: Interstitial dissolved Oxygen 48 49 50 Salmonids (a group a fish that contains species of salmon and trout) lay their eggs buried under the sand and gravel in streambeds. All life stages of salmonids use oxygen dissolved in water to meet their oxygen requirements, but the concentrations of dissolved oxygen (do) that the different life stages can survive vary. The most susceptible life stage to do concentrations are the eggs. Interstitial (meaning the area between sand/gravel grains in the sediment) do concentrations are often lower than in the stream, but is a limiting factor for egg metabolic activity. That makes the interstitial do concentration an important determinant if fish wil persist in a particular stream. 151 152 The Henry's Fork Foundation is concerned about monitoring the health of salmonids in the stream, including the ability of eggs to survive. [Henry's Fork is a tributary of the Snake River in Idaho]. They are interested if the population mean do concentration in the Henry's Fork is high enough for an salmonid egg to survive. Eggs that are 20 days post-fertilization (dpf) an oxygen concentration of 7.5 mg/L or greater for metabolic activity for normal development. They randomly choose locations on the stream (by overlaying a numbered grid on a map of the stream and then using a random number generator to choose numbered grid locations) to measure the interstitial do.
