Use the appropriate applet to construct a simulated null distribution using the slope of the least squares regression line as the statistic. Mark the observed least squares slope on this graph.
a. Paste a screenshot or draw your null distribution below with the observed slope marked and the approximate p-value shaded in.
b. Is the observed statistic out in the tail of this null distribution or is it a fairly typical result?
c. What is the p-value from your simulation? Based on this simulation analysis, would you conclude that the data provide strong evidence against the null hypothesis and conclude that there is a signifi cant association between hand span and number of Tootsie Rolls grabbed? Explain your reasoning.

Is hand span a good predictor of how much candy you can grab? Using 45 college students as subjects, researchers set out to explore whether a linear relationship exists between hand span (cm) and the number of Tootsie Rolls* each subject could grab.
