To create a scatter plot, draw a line of best fit, and interpret the slope and y-intercept, you would need a question that allows for paired numerical data. Based on the options provided, the only suitable question is:
- How is college student enrollment changing over the last century? - This question implies a quantitative analysis over time, which can yield numerical data to plot (e.g., enrollment numbers over different years).
The other options do not meet the criteria for gathering paired numerical data suitable for a scatter plot:
-
How tall are the students in your grade level at school? - This might provide data, but it is a single variable and not a relationship between two variables.
-
Was your height greater than 60 cm before your last birthday? - This is a yes/no question and does not provide numerical data for plotting.
-
What kind of car does your family drive? - This is categorical data, not suitable for a scatter plot.
-
What is your favorite color? - This is also categorical data, not suitable for a scatter plot.
-
What percentage of families in Florida had a radio in 1930? - This is a single statistic, not a question that would allow for a relationship to be plotted.
In summary, the first question is the only one that fits the purpose of creating a scatter plot and analyzing the data statistically.
