The signal output from a certain process in an industry is described by the following equation

h (t) = 5 cos 2π1000 t + 7 cos 2π 2000 t + 2 cos 2π 3000 t.

If the above signal h(t) is sampled at the rate of 5000 samples/second, comment on the output obtained from the reconstruction process.

A student group claims that first-year students at a university should study 2.5 hours (150 minutes) per night during the school week. A skeptic suspects that they study less than that on the average. A survey of 51 randomly selected students finds that on average students study 138 minutes per night with a standard deviation of 32 minutes. What conclusion can be made from this data? Select one:

A) The p-value is greater than .05, therefore we do not have enough evidence to conclude that students study less than 150 minutes per night.

B) The p-value is less than .05, therefore we conclude that students study greater than 150 minutes per night.

C) The p-value is less than .05, therefore we conclude that students study less than 150 minutes per night.

D) We do not have enough information to make a conclusion about this study. The p-value is less than .05, therefore we do not have enough evidence to conclude that students study less than 150 minutes per night.

Caroline was employed as a receptionist for ABC Corporation. Her desk was located at the entrance of the corporate office and her duties were to greet customers, answer telephone calls, sort mail, and respond to general requests for information about ABC. One day, while all of the managers of ABC were out of the office, a representative of XYZ Insurance Co. stopped by to solicit ABC as a new client. He told Caroline that he wanted to find out whether ABC might be interested in canceling its present employee health insurance plan and adopting a plan provided by XYZ. Although Caroline explained that none of the ABC managers were in the office, the XYZ representative nevertheless described his company’s health insurance plan in detail. When Caroline reacted by stating that XYZ’s plan sounded better than the current ABC plan, the XYZ representative immediately produced a contract for Caroline to sign. Reluctantly, Caroline signed the contract accepting the offer to adopt XYZ’s insurance plan. If XYZ seeks to enforce the contract against ABC, is ABC bound to the contract?

A swim club is designing a new pool to replace its old pool. The new pool would need to last for 10 years since the club is planning on relocating after 10 years. A concrete shell would cost $85,000 and last for all 10 years. Another option is to install a vinyl liner that would cost only $70,000 to install. However, the vinyl is not guaranteed to last for all 10 years, and it has a 40% chance of breaking down. Repair of the vinyl would cost $40,000 and would extend the life of the vinyl liner to the 10-year mark. If both options are acceptable to the swim club, which one minimizes cost?
