quantitative data - Answer Quantitative data consists of data values that are numbers, representing quantities that can be counted or measured. The Empirical Rule - Answer According to The Empirical Rule, approximately 68% of the data points in a dataset will be within 1 standard deviation of the mean. 95% of all values are within 2 standard deviations of the mean. Normal distribution - Answer In a normal distribution data is symmetrical, so the mean, median, and mode are all equal. mea...

1. Comment on the study design. In particular, is this an observational study or experimental study? What kind of inference or interpretation can you make? Is it possible to establish a causal link between the speed limit increases and the change in interstate traffic fatalities using this data? What is the population of interest? Can the findings be generalized to this population? This is an observational study as the data has been collected from previous study and the researcher has had ...
