Refer to Data Set 6 in Appendix B, and use the brain volumes (cm3) and IQ scores. A simple hypothesis is that people with larger brains are more intelligent and thus have higher IQ scores. Does the scatterplot support that hypothesis?
Answer to relevant QuestionsRefer to Data Set 7 in Appendix B, and use the measured chest sizes and weights of bears. Does there appear to be a correlation between those two variables? Refer to Data Set 14 in Appendix B, and use the greenhouse gas (GHG) emissions from the sample of cars. Does the configuration of the points appear to suggest that the amounts are from a population with a normal ...Use the frequency distribution from Exercise 24 in Section 2-2 to construct a frequency polygon. Applying a strict interpretation of the requirements for a normal distribution, do the depths appear to be normally ...Construct the histogram that corresponds to the frequency distribution from Exercise 1. Applying a very strict interpretation of the requirements for a normal distribution, does the histogram suggest that the data are from ...Use the frequency distribution from Exercise 6 to construct a histogram. Based on the result, do the data appear to be from a population with a normal distribution? Explain.
