In arepresentative study, a sample of n = 100 adolescentswith a history of group participation is given a stan-dardized self-esteem questionnaire. For the generalpopulation of adolescents, scores on this questionnaireform a normal distribution with a mean of p%3D50 and%3D15. The sample of group-a standard deviation of o%3Dparticipation adolescents had an average of M = 53.8.

Here it is given that , In a representative study, a sample of n = 100 adolescents with a history of group participation is given a standardized self-esteem questionnaire. For the general population of adolescents, scores on this questionnaire form a normal distribution with a mean of µ is = 50 and a standard deviation of σ = 15. The sample of group participation adolescents had an average of M = 53.8. That is , Population mean , µ = 50. Population standard deviation , σ = 15. Sample mean , M = 53.8. Sample size , n = 100. It is asked to find Compute Cohen's d to measure the size of the difference. Describing the outcome of the hypothesis test and the measure of effect size.It is asked to calculate the Cohen's d to measure the size of the difference. The formula to calculate Cohen's d is as follows; Cohen's d = M-µσ Now plug values and calculate this. Cohen's d = 53.8-5015=0.2533 Thus , the Cohen's d to measure the size of the difference is equal to 0.2533.It is asked to describing the outcome of the hypothesis test and the measure of effect size as it would appear in a research report. Explanation for this is as follows; Here there is no value given for significance level so we will consider this as 0.05. This hypothesis test gives a p-value (0.011406 ) is less than the level of significance (0.05). It simply means that the result is significant. Also this means that self-esteem scores for the group is significantly different from those of the general population. Simply we can say that the sample is large enough to support the hypothesis as p < 0.05 and also the Cohen's is showing minimum differences as the sample size changes.

Researchers investigate how the presence of cell phones influence the quality of human interaction. Subjects are randomly selected from a population and divided into an experimental group that is asked to leave their phones in the front of the room and a control group that are not asked to leave their cell phones at the front of the room. Subjects are left alone for 10 minutes and then asked to take a survey designed to measure quality of interactions they had with others in the experiment. What statistical test is appropriate?
A game manufacturer believes they have created a better game to help kids learn to type on a keyboard. A small group of kids was tested using the previous version of the game (2019) and the newer version (2020). Each time, the total number of words typed in 3 minutes by each child was recorded. Results are shown in the table below. Is there an improvement in the average number of words typed using the 2020 game? (Conduct a hypothesis test with an alpha-level of 0.05.

Dr. Mackintosh believes a new olfactory therapy would be more successful in promoting weight loss among obese patients. His patients are first weighed and then randomly assigned to olfactory therapy, dance therapy, or a control condition. At the end of the three weeks, the amount of weight lost is recorded. The results indicate no significant difference in the amount of weight lost between the three conditions. If true differences existed between the conditions, but they were not detected, what kind of error occurred?
There is some research to indicate that different dog breeds differ in emotionality. To consider these differences, a researcher administers a standard test of emotionality to 3 breeds of dogs (German Shepherd, Cocker Spaniel, and Chihuahua), with 4 dogs from each breed being tested. Higher scores mean higher emotionality. The results for the emotionality test scores appear below. Using the 7 steps of hypothesis testing, test the idea that there are differences in emotionality based on dog breed using α = .05 Emotionality Scores for Dogs German Shepherd Cocker Spaniel Chihuahua 6 0 10 1 4 12 7 0 9 2 0 8 T = 16 T = 4 T = 39 Gt = 59 N = 12 ∑x2 = 495 4.
