### Understanding Personality Traits Among Hotel ManagersSuccessful hotel managers must exhibit personality traits traditionally viewed as feminine (like being "compassionate") and those seen as masculine (such as being "forceful"). The Bem Sex-Role Inventory (BSRI) is a tool used to measure these traits, offering separate scores for "feminine" and "male" characteristics, each ranging from 1 to 7. Although designed during times of more pronounced gender stereotypes, the BSRI is still commonly used to assess masculinity and femininity in individuals. However, these scores are often summarized simply as femininity and masculinity ratings.In a recent study involving 148 male general managers from three-star and four-star hotels, the average BSRI femininity score was $\bar{x} = 5.29$. By comparison, the mean femininity score for the general male population is $\mu = 5.19$. This raises the question: do hotel managers exhibit significantly different femininity scores compared to the general male population? For this analysis, assume the standard deviation of scores among all male hotel managers is identical to that of the general adult male population, $\sigma = 0.78$.For further examination, you may find [Table A](#) helpful.

Successful hotel managers must have personality characteristics often traditionally stereotyped as feminine (such as "compassionate") as well as those traditionally stereotyped as masculine (such as "forceful"). The Bem Sex-Role Inventory (BSRI) is a personality test that gives separate ratings for "female" and "male" stereotypes, both on a scale of 1 to 7. Although the BSRI was developed at a time when these stereotypes were more pronounced, it is still widely used to assess personality types. Unfortunately, the ratings are often referred to as femininity and masculinity scores. A sample of 148 male general managers of three-star and four-star hotels had mean BSRI femininity score x 5.29. The mean score for the general male population is µ = 5.19. Do hotel managers, on the average, differ significantly in femininity score from men in general? Assume that the standard deviation of scores in the population of all male hotel managers is the same as the o = 0.78 for the adult male population. You may find Table A helpful.

You saw back in Chapter 2 that the mean, median, mode, and midrange are used to indicate where data is centered in a data set, or in other words what a typical value in the set is. A question that is often asked is, "If they're all supposed to do the same thing, why is there more than one?" Isn't one enough? In this exercise, you will be given two small sets of data. For each set, a. find the mean, median, mode and midrange b. in your opinion, decide which of the measures BEST represents all the values in the set (best indicates a typical value), and which one does this the WORST. c. post your responses and justify them by explaining why Don't forget to respond to at least one of your classmate's posts. With this exercise, "more is better."

In a study to determine the effect of early child care on infant-mother attachment patterns, 92 infants were classified as either "secure" or "anxious" using an appropriate measurement scale. In addition, the infants were classified according to the average number of hours per week that they spent in child care. The data are presented in the table.

“Bullying,” according to noted expert Dan Olweus, “poisons the educational environment and affects the learning of every child.” Suppose you are interested in the emotional well-being not only of the victims but also of bystanders, bullies, and those who bully but who are also victims (bully-victims). You decide to measure anxiety in a group of bullies and a group of bully-victims using an 18-item, 5-point anxiety scale. The group of 84 bullies scored an average of 40.1 with a sample standard deviation of 3.8 on the anxiety scale. The group of 67 bully-victims scored an average of 46.8 with a sample standard deviation of 11.6 on the same scale. Suppose you intend to conduct a hypothesis test on the difference in population means. In preparation, you identify the sample of bullies as sample 1 and the sample of bully-victims as sample 2. Organize the provided data by completing the following table:

"Fruit Juice May Be Fueling Pudgy Preschoolers, Study Says" is the title of an article that appeared in the San Luis Obispo Tribune. This article describes a study that found that for 3- and 4-year-olds, drinking something sweet once or twice a day doubled the risk of being seriously overweight one year later. The authors of the study state the following. Total energy may be a confounder if consumption of sweet drinks is a marker for other dietary factors associated with overweight.t Give an example of a dietary factor that might be one of the potentially confounding variables the study authors are worried about. O Children who drink sweet drinks have stricter parents who let them eat and drink whatever they want. Children who drink sweet drinks have more lenient parents who track their weight and focus on their health more. O Children who drink sweet drinks may also drink less each day than other kids. Children who drink sweet drinks may also eat a lot of sweet foods and high-calorie…

The U.S. National Center for Health Statistics complies birth statistics and publishes the results in vital statistics of the United States. The Center has historically believed that the mean of all newborns in the U.S. has been no less than 6.95 pounds. A sample of babies is selected so that the center can revise its belief. The following birth weights, in pounds are recorded: 7.4, 6.0, 8.6, 4.5, 2.0, 7.9, 4.0, 2.6, 5.9, 7.3, 7.3, 7.0, 6.3, 8.1, 7.1, 7.3, 6.6, 5.2, 9.8, 8.0, 10.9, 6.5, 3.8, 5.0, 8.0 a). At 5% level of significance, do these data provide sufficient evidence to refute the Center’s belief? Your conclusion must be in terms of the P-Value as well as setting up a Rejection Region. You must show all necessary work. b). Which statistical distribution should be applied in this situation and why? Explain carefully.
