Auniversity is interested in evaluating registration processes. students can register for classes by using either a telephone registration system or an online system that is accessed through the university's website. independent random samples of 80 students who registered by phone and 60 students who registered online were selected. of those who registered by phone, 58 reported that they were satisfied with the registration process. of those who registered online, 51 reported that they were satisfied. let p1 represent the proportion of students who were satisfied with the phone process and p2 represent the proportion who were satisfied with the on-line process. does the data support the claim that the proportion of satisfied students is lower for those who registered on the phone than for those who registered on line

Activity-based costing (abc) is not truly a cost collection mechanism as much as it is an inventory valuation method. the main purpose for implementing an activity-based cost system is to try to overcome some of the cost distortions that occur in traditional costing from product differences when there are variations in size and complexity. however, one of the disadvantages of utilizing abc is that the additional information gathering necessary to implement costing with that level of detail might be beyond the reach of some companies with resource or financial constraints. with this in mind, what kinds of industries or companies do you think would benefit most from using activity-based costing and why? in designing or modifying an accounting system to capture appropriate costs for abc, what considerations do you think would need to be made?
