A meta-analysis reports an average effect size of d = 0.11, with a confidence interval of d = 0.08 to d = 0.14. Would a hypothesis test (assessing the null hypothesis that the average effect size is 0) lead us to reject the null hypothesis? Explain.

Expert Solution

Summary : As the value specified by null hypothesis is not in the confidence interval, we reject null hypothesis.

Explain what a meta-analysis is (i.e., what is a meta-analysis in terms of effect sizes).

As the sample size INCREASES for computing a confidence interval, the width of the confidence interval DECREASES. 12 When the population standard deviation sigma is assumed known, a confidence interval can assume NORMALITY of the SAMPLE MEAN if the sample size is greater than 30. 12 A SYMMETRIC histogram implies the plotted variable is NORMALLY distributed. 12 The goal when using confidence intervals is to have WIDE INTERVALS to be assured that the interval contains the population parameter. 12 A...

Using either hypothesis testing or confidence interval method solve: The average size of a farm green county is 199 acres, and the average size of a farm in yellow county is 191. Assume the data were obtained from two samples with standard deviations of 12 acres and 38, respectively, and the sample sizes are 10 farms from Green county and 8 farms from in Yellow County. Can it be concluded at alpha= 0.05 that the average size of the farms...

Determine confidence intervals for each of the following: Sample Statistic Sample Size Confidence Level Confidence Interval Lower Boundary Upper Boundary Mean: 150 Std. Dev.: 30 200 95% Percent: 67% 300 99% Mean: 5.4 Std. Dev.: 0.5 250 99% Percent: 25.8% 500 99%

Describe the relationship between the width of a confidence interval and the size of the sample....

Describe the relationship between the width of a confidence interval and the size of the sample. Also describe the relationship between the width of the confidence interval and the degree of confidence. If a study yields an unsatisfactorily large confidence interval, what should be done? What prevents a researcher from continually increasing the sample size until a very small confidence interval is achieved?

2. What is the sample size, n, for a 95% confidence interval on the mean, if we know that the process’ standard error is 3.2 units, and we want to allow at most 1.0 units for our error? 3. Let’s say that you just randomly pulled 32 widgets from your production line and you determined that you need a sample size of 46 widgets, However, you get delayed in being able to pull another bunch of widgets from the line...

For this activity, you will be creating a confidence interval for the average number of hours of TV watched. You will also run a hypothesis test to test the claim that the average number of hours of TV watched is more than 7 hours. Students from a former MAT 152 class asked the question, “How many hours of TV do you watch in a typical week?” Please use the data they collected to answer the following questions. Data: 15, 11,...

The owner of a factory wants to determine a confidence interval for the average wages at his factory. The population average wages is unknown. However, the owner was able to take a random sample of 64 workers. He found that the average salary for this sample of workers is $50,000. The population standard deviation is $3000. He calculated a 99% confidence interval for the population average wages at the factory. Which of the following choices is correct? Assume the distribution...
