Squidward loves playing his clarinet and believes it attracts more jellyfish than any other instrument he has played. In order to test his hypothesis, Squidward played a song on his clarinet for a total of 5 minutes and counted the number of jellyfish he saw in his front yard. He played the song a total of 3 times on his clarinet, and then repeated the experiment using a flute and a guitar. He also recorded the number of jellyfish he observed when he was not playing an instrument. The results are shown in the chart. number of jellyfish attracted to each instrument trial / without music / clarinet / flute / guitar 1 / 5 / 15 / 5 / 12 2 / 3 / 10 / 8 / 18 3 / 2 / 12 / 9 / 17 1) what is the dependent value? 2) what is the independent variable? 3) what should be Squidward’s conclusion? 4) are the results reliable? why or why not?
