graphing scatterplots and trend lines\nbefore data is entered into the regression calculator, some data may be excluded. explain why the data pair (0, 100) was excluded for the comparison of hours slept the night before and the test score. describe what this data point represents. if it was included, would the trend line describe the data well?

Answer

Brief Explanations:

The data pair (0, 100) represents getting 0 hours of sleep the night before and still scoring 100 on a test. This is likely an out - lier as it is not in line with the general relationship between hours of sleep and test scores (usually more sleep is associated with better performance). If included, it could skew the trend line and make it less representative of the overall data set since it doesn't follow the expected pattern.

Answer:

The data pair (0, 100) is likely an outlier. It represents getting 0 hours of sleep and scoring 100 on a test. If included, the trend line would not describe the data well as it would be skewed by this non - typical data point.
