Electrical Heating Unit

The conversion of electrical energy to heat energy is known as electric heating. The heating system that converts the electrical energy to heat energy for various application is called electrical heating unit. Electricity is employed as the firing mechanism in electric heating systems, which transforms electric current to heat. Electric heaters have heating elements in the form of electric resistors.

Question

Determine the total DC resistance of the subscriber loop (including the telephone)

Scenario for Part 1:
A telecommunication company is tasked to design a subscriber loop that will follow the road map below to provide telephone services in a
subdivision. The initially designated service area interface (116 C. Lawis Extension) and the distribution point (San Luis, Antonio) are 3.7 km and
4.5 km, respectively, from the central office. One subscriber is 0.4 km from the distribution point (4.9 km from the central office).

A cable TV company was interested in making its operation more efficient by cutting down on the distance between service calls while still maintaining at least the same level of service quality. A treatment group of 18 repairpersons was assigned to a dispatcher who monitored all the incoming requests for cable repairs and then provided a service strategy for that day’s work orders. A control group of 18 repairpersons was to perform their work in a normal fashion—that is, by providing service in roughly a sequential order as requests for repairs were received. The average daily mileages for the 36 repairpersons are recorded in the table below. a. What are the populations of interest in this study?b. What is the level of significance of your test?c.
