Final answer:The statements regarding manual calculations of statistics before the 1980s, the definition of machine learning, and the requirements of engaging in the scientific method are all true. Statements about a box plot need further context to determine their accuracy, with typical interpretations often finding more nuanced answers than a simple true/false.Explanation:The question pertains to statistical analysis and involves understanding descriptive statistics, hypothesis testing, machine learning, and model updating within a statistical context.It appears that the student has been presented with various statements regarding these topics and needs to classify them as true or false, while also understanding concepts such as the initial model, data, test statistics, population parameters, and the significance level of hypothesis tests.Regarding the statement 'It is useful to note that up until the late 1970s and early 1980s, researchers had to calculate descriptive statistics and linear regressions by hand and with calculators', this statement is true. Before the widespread use of computers and statistical software, researchers had to perform these calculations manually, which was a time-consuming process.The statement 'Machine learning is the ability of a computer program to start with an initial model data, analyze actual data, learn from this analysis, and automatically update that initial model to incorporate the findings from its analysis' is also true. Machine learning involves algorithms that can learn from and make predictions on data by building models from sample inputs.Lastly, engaging in the scientific method does require researchers to participate in every stage, which includes hypothesizing, experimenting, observing, and analyzing, making the statement true.When interpreting statements about a given box plot:Statement A could be true if the lower quartile (25th percentile) value is five.Statement B is typically false as a box plot depicts medians and quartiles, not exact counts of data points within a range.Statement C is false unless the box plot explicitly shows no data at the value of three.Statement D is false - a box plot does not provide information about the exact percentage of data points at a single value, but rather percentages within intervals....
