Annual starting salaries for college graduates with degrees in business administration are generally expected to be between $10,000 and $40,000. Assume that a 95%
confidence interval estimate of the population mean annual starting salary is desired.
a. What is the planning value for the population standard deviation?
o =
b. How large a sample should be taken if the desired margin of error is $400? Round
your answers to next whole number.
150
$270?
$100?
X
c. Would you recommend trying to obtain the $100 margin of error? Explain.
No, the sample size would probably be too time consuming and costly.
How would I work this out?

In a study of the relationship between socio-economic class and unethical behavior, 129 university of california undergraduates at berkeley were asked to identify themselves as having low or high social-class by comparing themselves to others with the most (least) money, most (least) education, and most (least) respected jobs. they were also presented with a jar of individually wrapped candies and informed that the candies were for children in a nearby laboratory, but that they could take some if they wanted. after completing some unrelated tasks, participants reported the number of candies they had taken. it was found that those who were identiď¬ed as upper-class took more candy than others. in this study, identify: (a) the cases, (b) the variables and their types, (c) the main research question, (d) identify the population of interest and the sample in this study, and (e) comment on whether or not the results of the study can be generalized to the population, and if the ď¬ndings of the study can be used to establish causal relationships.
