A researcher wants to examine the effectiveness of a new reading program for students with poor reading skills. She recruits 100 students in eighth grade with poor reading skills for the study. Half the subjects participate in the new reading program while the other half of the subjects participate in the regular reading program. After a semester, all 100 students are assessed for their reading skills to determine whether the new reading program works better than the regular reading program....
2. A new reading program was being evaluated in the fourth grade at an elementary school. A random sample of 35 students was tested on a fixed-length reading passage in order to measure their reading speed. The average reading time of the sample of 35 students was 9.5 minutes with a standard deviation of 2.5 minutes. A. Estimate the mean reading speed for all fourth-grade students in this clementary school. Use a 95% confidence level. (15) B. If a larger...

A group of researchers has developed a method that they hypothesize will improve the reading ability of at-risk 1st grade students. They randomly selected nine students to participate in their study. The nine students were administered a reading test, then trained for 10 weeks using the new reading program, and then readministered the reading test. The following data are their scores: Subject 1st Reading 2nd Reading Score Score 1 23 19 2 20 19 3 24 21 4 24 24 5 24 22 6 19 17 7 17 15 8 18 16 9 20 18 What...
An educator believes that new reading activities for elementary school children will improve reading comprehension scores. She randomly assigns third graders to an eight-week program in which some will use these activities and others will experience traditional teaching methods. At the end of the experiment, both groups take a reading comprehension exam. Their Scores are shown below. New Activities: 23, 34, 34, 34, 35, 37, 42, 43, 44, 46, 47, 48, 49, 55 Control: 12, 13, 22, 26, 29, 30,...
5. A study is planned to assess the effectiveness of a new combination drug for treating nephrolithiasis (kidney stone). One hundred patients with nephrolithiasis will be randomly assigned to receive either the new combination drug or the standard surgical intervention. The efficacy of the new drug will be measured by the time it takes a patient to return to normal activities, measured in days. Identify the appropriate research design for this study a. Prospective cohort study b. Randomized controlled trial...
