D For the remaining questions on the project, you will need to use the Distribution tools on your calculator. We will be working with more exact values than the Empirical Rule can give us. For all but one of the remaining questions you will need to do your work on paper and embed the picture of your work in the answer box. You will need to show 1) your sketch of the normal curve; 2) your calculator entry; 3) your probability notation; and 4) your final answer in a sentence. We will continue to use the information about average sleep per night for high school students, where we assume this normal model applies to all high school students and we use u = 7.2 and o = 1.5.

Question 10 4 pts What would be the z-score for a student who averaged 6.5 hours of sleep on school nights? Show your work, and round to 2 decimal places if necessary (you may type in your work, OR you may do it on paper and embed a picture). In addition to giving the Z-score, interpret what the z- score means in this situation about high school students sleep. Edit View Insert Format Tools Table 12pt Paragraph BI V A TY .

Question 11 4 pts What is the probability that a randomly selected student averaged less than 6.5 hours of sleep on school nights? Round your answer to 4 decimal places. In the space below, embed a picture of your answer. Be sure to include:1) your sketch of the normal curve with appropriate labeling & shading (done by hand); 2) your calculator entry; 3) your probability notation; and 4) your final answer in a sentence.
