Answer:
it is paired sample t test.
here difference between 2 samples is given we want to estimate the mean difference for the population.
point estimae is the mean difference for the samples.
Mean difference = 18
Answer = 18

A researcher obtains a sample of n = 25 students and measures each individual's reading performance two times: before and after implementation of a new special reading program. The data will be used to estimate the mean amount of improvement. Which equation should the researcher use? O A. the single-sample t equation B. the independent-measures t equation c. the repeated-measures t equation D. cannot determine without additional information
10. The stimulant Ritalin has been shown to increase attention span and improve academic performance in children with ADHD (Evans et al., 2001). To demonstrate the effectiveness of the drug, a researcher selects a sample of the disorder and measures each child's attention span before and after taking the drug. The data show an average increase of attention span of Mp = 4.8 minutes with a variance of s2 125 for the sample of difference scores. 20 children diagnosed with...
5, Does playing Mozart to unborn babies make them smarter? A psychologist obtains a random sample of 20 mothers in the first trimester of their pregnancy. The mothers play Mozart in the house each day until they give birth. After 5 years, the child is administered an IQ test and the mean IQ scores for the children is 112 with a standard deviation of 18. Does playing Mozart to babies before they are born make them smarter than the population...
To evaluate the effect of a treatment, a sample of n-8 is obtained from a population with a mean of ?-50, and the treatment is administered to the individuals in the sample. After treatment, the sample mean is found to be M 55. a) If the sample variance is s-32, use a two-tailed test with ?-0.05 to determine whether the treatment effect is significant and compute Cohen's d b) If the sample variance is s- 72, repeat the test and...

Question 16 2 pts The population mean for a standardized test is 250. A research study with N = 30 adults from Virginia had a mean score of 260, with a 95% confidence interval of the mean reported as [248, 272]. What decision should be made based on this confidence interval? o Run the hypothesis test again o Accept the research hypothesis o Reject the null hypothesis o Fail to reject the null hypothesis Question...

1. We reject the null hypothesis only when: a. our sample mean is larger than the population mean. b. the p value associated with our test statistic is greater than the significance level of the test we have chosen. c. our sample mean is smaller than the population mean. d. the p value associated with our test statistic is smaller than the significance level of the test we have chosen. 2. In a study of simulated juror decision making, researchers...
My Ask You C-reactive protein (CRP) is a substance that can be measured in the blood. Values increase substantially within & hours of an infection and reach a peak within 24 to 48 hours after. In adults, chronically high values have been linked to an increased risk of cardiovascular disease. In a study of apparently healthy children aged 6 to 60 months in Papua New Guinea, CRP was measured in 90 children. The units are milligrams per liter (mg/l). Here...
