Theaverage age for licensed drivers in the county is u = 40.3 years with a standard deviation ofо%3D13.2 years.A researcher obtained a random sample of n = 16 parking tickets and computed an average age ofM=38.9 years for the drivers. Compute the Z-score for the sample mean and find the probabilityof obtaining an average age this young or younger for a random sample of licensed drivers. Is itreasonable to conclude that this set of n= 16 people is a representative sample of licensed drivers?Problems from textbook ch. 8 (#4, 15)5. Childhood participation in sports, cultural groups, and youth groups appears to be related toimproved self-esteem for adolescents (McGee, Williams, Howden-Chapman, Martin, & Kawachi,2006). In a representative study, a sample of n= 100 adolescents with a history of groupparticipation is given a standardized self-esteem questionnaire. For the general population ofadolescents, scores on this questionnaire form a normal distribution with a mean of u = 50 and astandard deviation of o = 15. The sample of group-participation adolescents had an average of M=53.8.Apply the 4 steps of the hypothesis testing procedure to determine whether this sampleprovide enough evidence to conclude that self-esteem scores for these adolescents aresignificantly different from those of the general population? Use alpha = .05.Compute Cohen's d to measure the effect size. What does the result tell us?6 Doconrnhors boTTO notod adoolina in noanitiro fnotioning/3O Oahp
