A standardized test has a scale that ranges from 3 to 45. A new type of review course for the test was developed by a training company. The accompanying table shows the scores for nine students before and after taking the review course. Complete parts (a) through (d) below. E Click the icon to view the data table. a. Perform a hypothesis test using a= 0.05 to determine if the average test score is higher for the students after the review course when compared with before the course. Let p, be the population mean of matched-pair differences for the score before the course minus the score after the course. State the null and alternative hypotheses. Choose the correct answer below. O A. Ho: Ha = 0 H,: Ha #0 O B. Ho: Ha 20 H,: Hg 0 H,: Ha s0 O D. Ho: Ha s0 H,: Hg>0 OF. Ho: Ha <0 H,: Hg 20 Test Scores O E. Ho: Ha #0 H,: H = 0 Student Before After 26 28 b. Calculate the appropriate test statistic and interpret the results of the hypothesis test using a = 0.05. 23 25 18 16 The test statistic…

In Exercises, hypothesis tests are proposed. For each hypothesis test, a.identify the variable.b.identify the two populations.c.identify the pairs.d.identify the paired-difference variable.e.determine the null and alternative hypotheses.f.classify the hypothesis test as two tailed, left tailed, or right tailed. TV Viewing. The A. C. Nielsen Company collects data on the TV viewing habits of Americans and publishes the information in Nielsen Report on Television. Suppose that you want to use a paired sample to decide whether the mean viewing times of married men and married women differ.

Determine the first step of hypothesis testing, and explain the procedure and logic of this step. Choose the correct answer below. A. The first step is to determine the level of significance at which to conduct the hypothesis test. The conventional levels of significance used are 5% and 1%, which are described as the 0.05 significance level and the 0.01 significance level, respectively. When a sample score is so extreme that researchers reject the null hypothesis, the result is said to be statistically significant. B. The first step is to restate the question as a research hypothesis and a null hypothesis about the populations. Since researchers are interested in the results in terms of the population, it is useful to restate the research question in terms of populations. The research hypothesis represents the research question being asked. C. The first step is to determine the characteristics of the comparison distribution. The overall logic of hypothesis…
