I don't know what questions #14a-h are, but looking at the answers:
I see that your hypothesis was that the salt would make photosynthesis work more slowly. Why did you think that? Even when the hypothesis seems to be wrong (happens more often than not in science!) you should always try justify your hypotheses. Example: We believed that the addition of 0.25% salt to the water would decrease the rate of photosynthesis because [insert reason: do plants dislike salt? does salt hurt the chloroplasts?].
For statistical analysis, has your class talked about taking the averages of trials and making graphs? You can quickly make graphs online: https://nces.ed.gov/nceskids/createagraph/ or https://www.onlinecharttool.com/graph?selected_graph=line. I'm uploading an example that I made with only the data of the second trial (you would have to get the averages of your trials).
