a Give bounds on the attained significance level.
b Applet Exercise Determine the exact p-value.
c Based on your answers to parts (a) and/or (b), what would you conclude at the \(\alpha=05\) level of significance?
d Would you expect the relationship between y and x to be linear if x were varied over a wider range, say, from x = 4 to x = 48?
e Give a 95% confidence interval for the slope. Provide a practical interpretation for this interval estimate.
