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), the reason for it, and write an appropriate conclusion, using complete sentences. iAlpha: iiDecision: iiiReason for decision: ivConclusion: iConstruct a 95% Confidence Interval for the true mean or proportion. Include a sketch of the graph of the situation. Label the point estimate and the lower and upper bounds of the Confidence Interval.
