A study was designed to determine whether video game players are better than non-video game players at crossing the street when presented withdistractions. Participants (college students) entered a street-crossing simulator. The simulator was designed to have cars traveling at various highrates of speed in both directions. During the crossing, the students also performed a memory task as a distraction. The researchers found thatstudents who are video game players took an average of 5.6 seconds to cross the street, with a standard deviation of 0.6 seconds. Assume that thetime, x, to cross the street for the population of video game players has μ = 5.6 and o=0.6. Now consider a sample of 40 students and let x representthe sample mean time (in seconds) to cross the street in the simulator. Complete parts a and b below.a. Find P(x>5.8).P(x>5.8) = (Round to three decimal places as needed.)

In a recent survey, ice cream truck drivers in Cincinnati, Ohio, reported that they make about $280 in income on a typical summer day. The income was generally higher on days with longer work hours, particularly hot days, and on holidays. The accompanying data file includes five weeks of the driver's daily income (Income), number of hours on the road (Hours), whether it was a particularly hot day (Hot - 1 if the high temperature was above 85°F, 0 otherwise), and whether it was a Holiday (Holiday = 1,0 otherwise). Click here for the Excel Data File a-1. Estimate the effect of Hours, Hot, and Holidays on Income. Report the regression coefficients and their significance at the 5% level. Note: Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.

A report suggests that business majors spend the least amount of time on course work than other college students (The New York Times, November 17, 2011), A provost of a university conducts a survey of 50 business and 50 nonbusiness students. Students are asked if they study hard, defined as spending at least 20 hours per week on course work. The response shows "yes" if they worked hard or "no" otherwise; a portion of the data is shown in the following table. Business Majors Nonbusiness Majors Yes No No Yes No Yes Yes Yes At the 5% level of significance, determine if the percentage of business majors who study hard is less than 20%? At the 5% level of significance, determine if the percentage of nonbusiness majors who study hard is more than 20%.

Dr. Jones conducted a study examining the relationship between the amount of sugar in a child’s diet and the activity level of the child. A sample of 30 four-year-old children from a local preschool was used in the study. Sugar consumption was measured by interviewing the parents about each child’s diet. Based on the result of the interview, each child was then placed into one of two groups: high sugar consumption and low sugar consumption. Activity level was measured by observing the children during a regular preschool afternoon. Finally, Dr. Jones compared the activity level for the high-sugar group with the activity level for the low-sugar group. Explain why Dr. Jones’ study is not an example of the experimental research strategy and provide way that it can be tested experimentally.
You survey college bound and find that 85% plan to liv eon campus, 35% plan to have a car while at campus and 5% plan to live off campus and not have a car. Is there an association between living on campus and having a car at college?
In the Chapter Preview we presented a study showing that handling money reduces the perception pain (Zhou, Vohs, & Baumeister, 2009). In the experiment, a group of college students was told that they were participating in a manual dexterity study. Half of the students were given a stack of money to count and the other half got a stack of blank pieces of paper. After the counting task, the participants were asked to dip their hands into bowls of very hot water (122°F) and rate how uncomfortable it was. The following data show ratings of pain similar to the results obtained in the study.

A campus researcher wanted to investigate the factors that affect visitor travel time in a complex, multilevel building on campus. Specifically, he wanted to determine whether different building signs (building maps versus wall signage) affect the total amount of time visitors require to reach their destination and whether that time depends on whether the starting location is inside or outside the building. Three subjects were assigned to each of the combinations of signs and starting locations, and travel time in seconds from beginning to destination was recorded. How should the data be analyzed? Wall Signs Map Starting Room Interior 141, 119, 238 85, 94, 126 Randomized block design O Completely randomized design 2 x 2 factorial design Levene's test Exterior 224, 339, 139 226, 129, 130
New Zealand requires cyclists to wear cycle helmets on public roads and this is enforced with fines. Most other countries have no mandatory helmet law, and a few have a law but do not enforce it. Finland is an example of a country that has a mandatory cycle helmet law but does not enforce it. A road safety researcher is interested in whether the proportion of cyclists in New Zealand do actually wear helmets is different to the proportion of cyclists in Finland who wear helmets. She has data from a survey which gives the following information: New Zealand: Of 210 New Zealand cyclists surveyed, 100 wear a helmet while cycling. Finland: Of 630 Finnish cyclists surveyed, 290 wear a helmet while cycling. Say that the true population proportion of New Zealand cyclists who wear a helmet is p1 and the true population proportion of Finnish cyclists who wear a helmet is p2. If our null hypothesis is H0: p1 - p2 = 0 and our alternative hypothesis is Ha: p1 - p2 ≠ 0, what is the z test…
An educational psychologist was interested in whether using a student’s own name in a story affected children’s attention span while reading. Six children were randomly assigned to read a story under ordinary conditions (using names like Dick and Jane). Six other children read versions of the same story, but with each child’s own name substituted for one of the children in the story. The researcher kept a careful measure of how long it took (in minutes) each child to read the story. The results are shown in Table 2. Using the 0.05 alpha level, does including the child’s name make any difference? Use all of the steps of hypothesis testing.

A researcher is interested in studying the effects of altitude on cognitive performance (e.g., perception, memory, problem solving, etc.). The researcher finds a group of experienced mountain climbers (n = 10) who volunteer to participate in the study. All of the climbers are tested at three different altitudes—at sea level (in the researchers’ laboratory at the University of California, San Diego), at the base camp (9,000 feet above sea level), and at 23,000 feet above sea level (at the peak of Mt. Denali in Alaska). At each location, the climbers perform a memory task (remember a list of 16 non-words like “biv”), and the accuracy of their memory is recorded (i.e., # of correctly recalled words). a. pls name the independent variable, dependent variable, levels of the IV, and the type of experiment design of this study (i.e., b/w- or w/i-subject design ) b. on what level of measurement is accuracy of memory assessed? (i.e., is it on nominal, ordinal, interval, or ratio?
