1. In a psychological study of distance perception, introductory psychology class volunteerswere given either 5 or 10 extra credit points depending on their level of participation inthe experiment. They walked along paths laid out along hallways in the psychologybuilding, and were asked to judge the distance they had walked. Each path distance wasbetween 100 and 200 feet in length, and contained from two to seven 90 degree turns.The investigators also kept track of class standing (freshman, sophomore, junior, orsenior) of each participant. For each of the variables in the study, determine whether it isqualitative or quantitative. For each quantitative variable, determine whether it is discreteor continuous. For each qualitative variable, determine whether it is nominal or ordinal.[4 pts.]a. The true length of the pathb. The amount of credit given to volunteersc. Class standingd. The number of 90 degrees turns2. In a survey of exercise habits, 1500 national adults were selected randomly and contactedby telephone. Respondents were asked, "Typically, how many hours per week do youexercise?" On average, those surveyed exercised 1.3 hours per week. Answer thefollowing questions. [0.5+0.5+1 pts.](a) The number 1500 is the size of the stratified(b) The number 1.3, is it a parameter or statistic?(c) What is the target population?being studied.
