<strong>STAT</strong> <strong>350</strong> <strong>Lab</strong> 3 <strong>Assessing</strong> <strong>the</strong> <strong>Normality</strong> <strong>of</strong> <strong>Data</strong> <strong>Solution</strong> (<strong>2018</strong>) - <strong>Purdue</strong> <strong>University</strong><br />

A. (10 points) Online Prelab<br />

B. (10 points) Normal random numbers (no data file required) Use s<strong>of</strong>tware to generate 10<br />

observations from a normal distribution with mean, μ = 9 and standard deviation, σ = 4.5.<br />

1. (3 pts.) Code:<br />

2. (3 pts.) Make a histogram <strong>of</strong> <strong>the</strong>se observations. How does <strong>the</strong> shape <strong>of</strong> <strong>the</strong> histogram<br />

compare with a normal density curve?<br />

3. (4 pts.) Make a normal probability plot <strong>of</strong> <strong>the</strong> data. Does <strong>the</strong> plot suggest any important<br />

deviations from normality? Please provide specifics to explain your answer.<br />

C. (10 points) Normal random numbers (no data file required) Use s<strong>of</strong>tware to generate 100<br />

observations from a normal distribution with mean, μ = 9 and standard deviation, σ = 4.5.<br />

D. (40 points) Random numbers from o<strong>the</strong>r distributions (no data file required)<br />

E. (15 points) Comparison <strong>of</strong> data – GROUP (submitted separately on Blackboard)<br />

F. (15 points) The distribution <strong>of</strong> Assaults Per Population (data file: Clean US <strong>Data</strong>)
