The Bluebottle (Physalia physalis) is a marine stinger # # Handedness Sail_Height Bluebottle_Length resembling a jellyfish, which is commonly seen in the # # Right 0.7 5.4 ocean or washed up on the beaches around Australia. # # Left 0. 5 4.3 Unfortunately, its tentacle is venomous, and sometimes # # Left 0. 2 3.9 very painful. A new research project, Bluebottle Watch, Left 1.3 8.7 aims at predicting the arrival of the Bluebottle to shore. 4 # Right 0. 5 4.5 The Bluebottle does not swim, but is transported by the Left 1.0 6.9 ocean currents and the wind. When pointing forward, 1# Left 0.6 4.5 the bulge of the tentacles is either to the right or to # # Left 0. 2 5.5 the left of the sail, referred to as right-handed or left- # # Left 0.4 5.2 handed bluebottles, respectively. They are expected to # # Right 0. 5 8.5 drift in opposite directions when the wind blows. 1 # Right 0. 1 1.7 Within the project, specific beach surveys are dedi- # # Left 0.3 5.5 cated to the analysis of the handedness and size of 4 # Left 1.3 7.5 the Bluebottles in Maroubra and how they are re- # # Left 1. 4 6.9 lated, which is the data you have been sent in your # # Left 0.4 3.6 email. The beach surveys lasted a few days in OC- # # Left 0. 6 9.2 tober 2022, and consisted in randomly picking Blue- 4 # Left 0.6 2.7 bottles on the beach with replacement (the rows in # # Left 0. 4 3.7 your dataset), noting whether they are right-handed or # # Left 0.5 3.9 left-handed (Handedness), and measuring their total Right 0.6 7.0 length (Bluebottle_Length in centimetres), and the Left 1.0 4.3 height of the sail (Sail_Height, in centimetres) which Left 0. 1 5.2 is believed to explain how fast they are pushed by the 1# Left 0. 2 5.0 wind. Note that, so far, we have no reason to believe Left 0.0 2.9 that Bluebottles in Maroubra are representative from # # Left 0.3 4.2 anywhere else. # # Left 0.4 4.3Briefly, list the main relationship that the researchers are trying to investigate with the beach surveys in Maroubra based on the scenario. What is the population here? What are the cases here? (We do not expect a list of all cases here.) What is the sample size? (We expect a value here.) Is it an observational study or is it an experiment? Provide a brief justification for your
