Class Time: Name: aHo size 12{H rSub { size 8{o} } } {}: _______ bHa size 12{H rSub { size 8{a} } } {}: cWhat are the degrees of freedom? dState the distribution to use for the test. eWhat is the test statistic? fWhat is the p size 12{p} {}-value? In 1 – 2 complete sentences, explain what the p size 12{p} {}-value means for this problem. gUse the previous information to sketch a picture of this situation. Clearly label and scale the horizontal axis and shade the region(s) corresponding to the p size 12{p} {}-value.

hIndicate the correct decision (“reject” or “do not reject” the null hypothesis) and write appropriate conclusions, using complete sentences. iAlpha: iiDecision: iiiReason for decision: ivConclusion:
