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 is the alternative hypothesis for the 1st grade Reading study?

    There are many ways to measure the reading ability of children. Research designed to improve reading performance is dependent on good measures of the outcomes. One frequently-used test is the DRP, or Degree of Reading Power. It is known that the distribution of DRP scores is normally distributed. A researcher suspects that the mean score µ of all third-graders in Henrico County Schools is different from the national mean, which is 32. To test her suspicion, she administers the DRP...

    In a study of the effectiveness of an arts appreciation class to improve student creativity, researchers randomly assigned 200 third-grade students to participate in an experimental arts program. Another 200 third-grade students were randomly assigned to participate in a traditional arts education program. At the end of the study, students were measured on a creativity test. The mean score for the treatment group was 78.5 and the mean score for the control group was 77.4. The researchers did significance test...

    The answers are marked but I need them explained. A new program designed to improve high school student reading comprehension has been launched in a major school district. Students can choose how many hours they spend participating in the program, as an alternative to some other elective courses. A researcher is interested in a possible linear relationship between the number of hours a student spends taking part in the program (X) and standardized reading test scores (Y). 100 students were...

    A test of reading ability has mean 60 and standard deviation 5 when given to third graders. Sixth graders have mean score 83 and standard deviation 11 on the same test. To provide separate "norms" for each grade, we want scores in each grade to have mean 100 and standard deviation 20. (Round your answers to two decimal places.) (a) What linear transformation will change third-grade scores x into new scores xnew = a + bx that have the desired...

    Researchers hypothesize that learning through imitation will improve self-care skills. For 6 months the researchers worked with mentally impaired individuals in which half were taught self-care skills through imitation and the other half through physically guided practice. At the end of the 6 months individuals were asked to independently perform the self-care task and were rated on the level of required assistance where a higher score means more assistance. What can the researchers conclude with an α of 0.01. The...

    The first two questions refer to the following information: Researchers developed an online tool to help ESL students learn prepositions and metaphors. A study measuring academic success in ESL students randomly sampled 100 Spanish speaking ESL students using traditional ESL classes and the new language tool and 81 Portuguese speaking ESL students using traditional ESL classes and the new language tool, and scored them on a common English fluency scale (higher score representing greater degree of fluency). The researchers suspected...

    codeblock c++ language Write a program that reads students test scores in the range 0-200 from a file until end of file (use e of() to check if ifstream reaches the End of File Stream) and store those scores in an array. It should then determine the number of students having scores in each of the following ranges: 0-24, 25-49, 50-74, 75-99, 100- 124, 125–149, 150-174, and 175–200. Finally, the program outputs the total number of students, each score range...

    1. Researchers want to examine the effect of scent on memory. A total of 9 people were recruited for the study. Each person randomly assigned to one of the three experimental groups. Each person was asked to read a passage from a book. A week later, each study participant was asked to recall as much information as they could from the previously read passage.  Researchers determined a score for each subject representing the facts that have been correctly recalled. The data...

    2. An experiment about a person’s ability to perform some task before and after taking one of the two drugs was conducted. The subjects performed the task that involved mental addition. The subjects were randomly divided into two groups. Each group drank a beverage containing one of two drugs, labeled A, B (placebo). After a period of time for the drugs to take effect, each subject repeated the mental addition test. We want to relate the after test score to...
