Reid Harper, the manager at Modix Hotel, makes every effort to ensure that customers attempting to make phone reservations do not have to wait too long to speak with a reservation specialist. Since the hotel accepts phone reservations 24 hours a day, Reid is especially interested in maintaining consistency in service. Reid wants to determine if the variance of wait time in the early morning shift (12:00 am – 6:00 am) differs from that in the late morning shift (6:00 am – 12:00 pm). He uses independently drawn samples of wait time for phone reservations for both shifts for the analysis; a portion of the data is shown in the accompanying table. Assume that wait times are normally distributed.

a. Select the hypotheses to test if the variance of wait time in the early morning shift differs from that in the late morning shift.


  • H0: σ12 / σ22 = 1, HA: σ12 / σ22 ≠ 1

  • H0: σ12 / σ22 ≤ 1, HA: σ12 / σ22 > 1

  • H0: σ12 / σ22 ≥ 1, HA: σ12 / σ22 < 1

b-1. Calculate the value of the test statistic. (Round intermediate calculations to at least 4 decimal places and final answer to 3 decimal places.)

b-2. Find the p-value.


c. At the 10% significance level, what is your conclusion?

  • Reject H0, since the p-value is more than α.

  • Reject H0, since the p-value is less than α.

  • Do not reject H0, since the p-value is less than α.

  • Do not reject H0, since the p-value is more than α.


d. Interpret the results at  α = 0.10.


  • The variance of wait time in the early morning shift is greater than that in the late morning shift.

  • The variance of wait time in the early morning shift is not greater than that in the late morning shift.

  • The variance of wait time in the early morning shift differs from that in the late morning shift.

  • The variance of wait time in the early morning shift does not differ from that in the late morning shift.

Medi Corp is a corporation that deals in the manufacturing of medical devices. It has just received a patent from the U.S. Patent and Trademark Office for one of its surgical robotic knee devices. The patent is for the purpose of use in full knee replacement surgeries, which was stated on the patent’s application. For part of the manufacturing process, Medi Corp uses Tech Co. to assemble the computer components that run the robot. Tech Co. is a computer company that manufactures a lot of the computer components for several medical device companies in the U.S.

Medi Corp has been considering making a bid to acquire Tech Co. If Medi Corp acquires Tech Co., the transaction would likely be around $100 million dollars. Tech Co. is one of only three companies in the U.S. that manufactures and assembles these computer components for medical devices, and is the biggest of the three companies that offer these services, with the other two companies several million in revenue behind Tech Co. Moreover, Medi Corp. is considered a leader in medical device manufacturing in the U.S. Both companies are publicly traded companies.

Tech Co.’s board of directors are willing to approve of a merger with Medi Corp. Rebecca is on the board of directors for Tech Co. She tells her husband that he should consider purchasing Medi Corp stock. Rebecca does not tell her husband any of the confidential information of the potential merger with Medi Corp., but her husband does know that she is on the board of directors at Tech Co. and that Medi Corp is a company Tech Co. does business with. Bob is an employee of Tech Co. He has been courted by Comp Inc., one of the competitors of Tech Co.

Bob has decided to leave Tech Co. for a senior placement at Comp Inc. At Tech Co., Bob works on the manufacturing of these computer components for Medi Corp. At Comp Inc., he will be in more of a management position, determining which companies Comp Inc. should be doing business with, and managing those employees that are in the manufacturing facilities.

Please answer the following question and provide legal reasoning:

If Medi Corp learns that Comp Inc. is releasing a robotic surgical device for hip replacement surgery that has similar technology to its surgical robotic knee devices, does it have any recourse against Comp Inc. for patent infringement? Please fully explain your answer as to what it must prove for this complaint against Comp Inc., and any defenses Comp Inc. has against this claim. Also explain if there could be any recourse against Bob directly if Bob had originally signed a confidentiality agreement with Tech Co. when he worked for them.
