Results of a Department of Education survey of SAT test scores in 22 states showed the following results. 11 states had an average composite test score of at least 1000 during the past 3 yr. 15 states had an increase of at least 10 points in the average composite score during the past 3 yr. 8 states had both an average composite SAT score of at least 1000 and showed an increase of at least 10 points during the past 3 yr. (a) How many of the 22 states had composite scores of less than 1000 and showed an increase of at least 10 points over the 3-yr period? states (b) How many of the 22 states had composite scores of at least 1000 and did not show an increase of at least 10 points over the 3-yr period? states

A government agency computed the proportion of U.S. residents who lived in each of four geographic regions in a particular year. Then a simple random sample was drawn of 1000 people living in the United States in the current year. The following table presents the results. Region Past YearProportion ObservedCounts Northeast 0.171 150 Midwest 0.245 235 South 0.357 398 West 0.227 217 Send data to Excel Can you conclude that the proportions of people living in the various regions changed between the current year and the past year?

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:
Researchers asked parents of 19 American children, ages 8 to 12, to complete surveys on the number of hours their children spent reading and the number of hours they spent on screen-based media time. Each of the children also underwent magnetic resonance imaging (MRI) to assess connectivity in the brain. More time spent reading was associated with higher connectivity, while more screen time was associated with lower connectivity in the brains of the children. 1. What is the sample in this study? c 2. What is a possible population? F6 3. Is this an experiment or an observational study? Why did you make that decision? 4. Can we conclude that more time spent reading increases connectivity in children's brains? 5.
