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.

An experiment investigated the effect of length and repetition of TV ads on students choosing to eat at Del Taco. All 60 students watched a 40-minute television program that included ads for Del Taco. Some students saw a 30-second commerical; others a 90-second commerical. The same commerical was shown either 1, 3, or 5 times during the program. After the viewing, each student was asked to rate their craving for Del Taco on a scale of 0 to 10. What is the response variable?A. 1, 3, or 5 commercials during the 40-minute television programB. craving for Del Taco on a scale of 0 to 10C. 60 studentsD. 30-second and 90-second commericialsE. 40-minute television program
Do people feel hungrier after sampling a healthy snack? Researchers randomly assign volunteers into one of three groups. The people in the first group were asked to taste a snack that was billed as a new health bar containing high levels of protein, vitamins, and fiber. The people in the second group were asked to taste the same snack but there told it was a tasty chocolate bar with a raspberry center. After tasting the snack, participants were asked to rate their hunger on a scale from 1 (not at all hungy) to 7 (very hungry). The people in the third group were asked to rate their hunger but were not given a snack. Healthy Tasty No Snack 8 3 3 7 1 3 7 3 5 4 2 6 5 6 5 a. Perform a complete one-way ANOVA hypothesis test.

Latoya has two ways to travel from her home in Norco to her office in Los Angeles. One is to go via the 10 Freeway, and the other is to go via 60 Freeway. In order to determine which way she should travel on a daily basis, Latoya has recorded the travel times for samples of nine trips via the 10 Freeway and nine trips via the 60 Freeway. The following table gives the travel times (in minutes) for the eighteen trips. Travel times in minutes 10 Freeway 71, 70, 69, 67, 71, 67, 70, 71, 77 60 Freeway 76, 74, 78, 78, 68, 73, 75, 72, 72 Send data to calculator Send data to Excel Assume that the two populations of travel times are normally distributed and that the population variances are equal. Can we conclude, at the 0.10 level of significance, that μ₁, the mean travel time via the 10 freeway, is different from μ2, the mean travel time via the 60 freeway? Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round…
