An airline's data indicate that 50% of people who begin the online process of booking a flight never complete the process and pay for the flight. To reduce this percentage, the airline is considering changing its website so that the entire booking process, including flight, seat selection, and payment, can be done in two pages rather than the current four. A random sample of 300 customers who begin the booking process are presented with the new system, and 117 of them do NOT complete the booking process. Based on this sample, do the data provide enough evidence to conclude that the new system has reduced the proportion of people who fail to complete the booking process?Conduct a hypothesis test at the 10% significance level. a. State the null and alternative hypotheses. b. Calculate the value of the test statistic. c. Draw the critical region and identify the critical value. d. Assess the evidence (e. g., does the test statistic fall into the critical region).e. State your conclusion in terms of the problem.

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.
