Carnivorans are a group of mammals that includes cats, dogs, bears, badgers and otters, among other species. Were prehistoric carnivoran species larger than modern carnivoran species that exist today? To answer this question, you collect data on the body masses of 56 carnivoran species (both extinct and modern). Go here to download or make a copy of the data to answer the questions below: https://bit.ly/ 3pxMLso The columns in this dataset are as follows: . Species: the scientific name of each species Status: whether the species is EXTINCT or MODERN . Mass_kg: the body mass of the species in k a) Determine the mean body mass, its SD, and its 95% confidence interval for the sample of EXTINCT species in this dataset (n = 26 species). [2 marks] b) Determine the mean body mass, its SD, and its 95% confidence interval for the sample of MODERN species in this dataset (n = 30 species). [2 marks] c) What shape is the distribution of body mass in this dataset? Using Excel or Google Sheets, make a graph that will allow you to determine this, and briefly describe the shape here. You do NOT need to provide your graph in your answer, just state the type of graph used and what you concluded about the shape of the distribution of this variable. [2 marks] d) What type of graph would you use to show the relationship between body mass and status (whether a species is modern or extinct)? Why is a bar graph NOT a good choice for this?
