1. The Student News Service at Clear Mountain State University (CMSU) has decided to gather data about the undergraduate students who attend CMSU. They ­create and distribute a survey of 14 questions and receive ­responses from 62 undergraduates (stored in UndergradSurvey ). For each numerical variable in the survey, decide whether the variable is approximately normally distributed by 

a. comparing data characteristics to theoretical properties.

b. constructing a normal probability plot.

c. writing a report summarizing your conclusions.

2. The dean of students at CMSU has learned about the undergraduate survey and has decided to undertake a similar survey for graduate students at CMSU. She creates and distributes a survey of 14 questions and receives responses from 44 graduate students (stored in GradSurvey). For each numerical variable in the survey, decide whether the variable is approximately normally distributed by 

a. Comparing data characteristics to theoretical properties. 

b. Constructing a normal probability plot. 

c. Writing a report summarizing your conclusions.
