The good statistical question that applies to gathering data for creating a scatter plot, drawing a line of best fit, and interpreting the slope and y-intercept in context would be:
D. What percentage of families in Florida had a radio in 1930?
To gather the necessary data, you would need to research historical records or data sources related to families in Florida in 1930. By collecting information on radio ownership percentages for different families during that time, you can create a scatter plot with the x-axis representing the families and the y-axis representing the percentage of families with a radio. Additionally, you can then draw a line of best fit to show the overall trend in radio ownership.
The slope of the line of best fit would indicate the rate of change in radio ownership over time. A positive slope would suggest an increasing percentage of families with radios, while a negative slope would indicate a decreasing percentage. The y-intercept, on the other hand, represents the estimated percentage of families with a radio in 1930 when the x-value (family) is zero.
Interpreting the slope and y-intercept in context, you can make conclusions about the historical trend in radio ownership among families in Florida in 1930 and how it changed over time.
