8. Childhood participation in sports, cultural groups,and youth groups appears to be related to improvedself-esteem for adolescents (McGee, Williams,Howden-Chapman, Martin, & Kawachi, 2006). 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. = 50 anda standard deviation of o = 15. The sample of group-participation adolescents had an average of M = 53.8.a. Does this sample provide enough evidence to con-clude that self-esteem scores for these adolescents%3D%3Dare significantly different from those of the generalpopulation? Use a two-tailed test with a =b. Compute Cohen's d to measure the size of thedifference..05.c. Write a sentence describing the outcome of thehypothesis test and the measure of effect size as itwould appear in a research report.

A graduate student is interested in how viewing different types of scenes affects working memory. For his study, he selects a random sample of 36 adults. The subjects complete a series of working memory tests before and after walking in an urban setting. Before the walk, the mean score on the test of working memory was 9.1. After the walk, the mean score was 1.4 higher. The graduate student has no presupposed assumptions about how viewing different types of scenes affects working memory, so he formulates the null and alternative hypotheses as: H00 : μDD = 0 H11 : μDD ≠ 0 Assume that the data satisfy all of the required assumptions for a repeated-measures t test. The graduate student calculates the following statistics for his hypothesis test: Mean difference (MDD) 1.4 Estimated population standard deviation of the differences (s) 1.6 Estimated standard error of the mean differences (sMDMD) 0.2667 Degrees of freedom (df) 35 The t statistic 5.25 The critical values of t…

The work week for adults in the US that work full time is normally distributed with a mean of 47 hours. A newly hired engineer at a start-up company believes that employees at start-up companies work more on average then most working adults in the US. She asks 12 engineering friends at start-ups for the lengths in hours of their work week. Their responses are shown in the table below. Test the claim using a 10% level of significance. Hours 47 47 55 51 48 65 51 52 50 49 51 54 What are the correct hypotheses? Ho: Select an answer ✓ ? ✓ Ha: Select an answer ✓ Test Statistic= hours Based on the hypotheses, find the following: p-value= hours (Give answer to at least 4 decimal places.) (Give answer to at least 4 decimal places).

A Bloomberg Businessweek subscriber study asked, "In the past 12 months, when traveling for business, what type of airline ticket did you purchase most often?" A second question asked if the type of flight was domestic or international travel. Sample data obtained are shown in the following table. Type of Flight Type of Ticket Domestic International First Class 26 21 Business Class 99 123 Economy Class 515 137 a. Using a 0.05 level of significance, is the type of ticket purchased independent of the type of flight? Ho: Type of ticket purchased is independent of the type of flight H.: Type of ticket purchased is not independent of the type of flight v Compute the value of the x test statistic (to 2 decimals). Use Table 3 of Appendix B to find the p-value. The p-value is - Select your answer - What is your conclusion? Conclude that the type of ticket purchased Select your answer - v the type of flight. b. Discuss any dependence that exists between the type of ticket and type of flight. I.…
A recent article in the Journal of Urban Chicken Farmers reported the fraction of chickens that experience severe, moderate, or minor side effects from a new diet are 0.07, 0.15, and 0.78 respectively. Assuming that chickens respond independently, if 18 chickens were tested on the new diet, what is the: 3. a. Mean number of chickens that will suffer severe side effects? b. Variance in the number of chickens that will suffer severe side effects? C.Conditional mean of the number of chickens that suffer severe side effects given that 17 suffer minor side effects.

Identify the statistical procedures that are appropriate for the data. Childhood participation in sports, cultural groups, and youth groups appears to be related to improved self-esteem for adolescents (McGee, Williams, Howden-Chapman, Martin & Kawachi, 2006) in a representative study, a researcher compares scores on a standardized self-esteem questionnaire for a sample of n = 100 adolescents with a history of group participation and a separate sample of n = 100 who have no history of group participation.
