Read the following on attendance and grades, and answer the questions. A study revealed that students from a certain local college in Bulacan who attended class 95 to 100% of the time usually received a grade of 1.0 in the class. Students who attended class 80 to 90% of the time usually received a 1.5 or 1.75 in the class. Students who attended class less than 80% of the time usually received a 3 or a 5 or eventually withdrew from the class. Many factors affect a student’s grade in a course. One factor that has considerable control over is attendance. One can increase the opportunities for learning by attending class more often. a. From the information given, comment on the relationship between the variables Answer: b. What type of survey do you think is most appropriately used for the study? Answer: c. Do you think the use a random method for deciding who would be in the sample is appropriate? Why? Answer:
A conservative radio talk show host with a large audience is interested in the proportion p ofadults in his listening area who think the drinking age should be lowered to eighteen. To findthis out, he poses the following question to his listeners: “Do you think that the drinking ageshould be reduced to eighteen in light of the fact that eighteen year‐olds are eligible for militaryservice?” He asks listeners to phone in and vote “Yes” if they agree the drinking age should belowered and “No” if not. Of the 100 people who phoned in, 70 answered “Yes.” a. List one source of sampling bias (i.e. bias based on the people included in the sample). b. List another source of bias (sampling or non-sampling).
A researcher wants to determine the percentage of American teenagers who send or receive text messages while doing homework. Which of the following techniques would likely be the MOST efficient way of obtaining an accurate estimate for this percentage? 1. Randomly select teenagers from the list of all teenage students in every state in America and mail surveys to those teens, asking them if they send or receive text messages while doing homework. 2. Send a survey to every teenager in America and ask them if they send or receive text messages while doing homework. 3. Randomly select teenagers from the list of all teenage students in one state and mail surveys to those teens, asking them if they send or receive text messages while doing homework.
A programmer plans to develop a new software system. In planning for the operating system that he will use, he needs to estimate the percentage of computers that use a new operating system.
