Introduction Airline carrier flight times vary slightly from carrier to carrier and even when the airport origins and destinations are the same. Is there a mean difference between San Francisco and Dallas Fort Worth Texas airport in the USA when comparing the flight time between Sky West (OO) and Virgin airlines (VX)? To answer this question, two randomly sampled groups were used to collect data for a two-sample test to conduct a hypothesis which would provide an answer about the mean. I will compare the means of Sky West and Virgin America Airline flight time between San Francisco and Dallas Fort Worth and compare them. I expect the test to reveal the airline with the fastest flight times between the two cities. Population The population that I intend to study is Sky West and Virgin Airlines. I will compare the two airlines and determine whether it’s faster to fly from San Francisco to Dallas Fort Worth using the air time in this T-test.
Variables
The two sample T test will use the air times variable for either Sky west Airlines or Virgin Airline to fly from San Francisco, California (SFO) airport to Dallas Fort Worth, Texas (DFW) airport.
Data Collection Data for this T test was collected from a file generated on the Research and Innovative Technology Administration Bureau of Transportation Statistics website, between two airlines, Sky West Airline and Virgin America Airlines flight between (SFO) San Francisco, CA International Airport and (DFW), Dallas Forth Worth Texas International Airport, and the difference between them to include the total air times which I used randomly for this test. I randomly selected 50 of 100 samples of total air times from each carrier list and tested them.
Study Design
Null Hypothesis (Ho): There is no significant difference in the population means in air time of Sky West and Virgin America

They also provide broadband and subscription television services. (en.wikipedia.org/wiki/AT&T) By the end of 2008, AT&T had discontinued and removed all of its pay telephones. With the decline in phone services, including traditional home phones, the company needed to develop new technologies. The company had to strategize a way back into the consumer’s residence. So, AT&T deployed a new media called U-Verse and extended its high-speed internet into rural areas. ( en.wikipedia.org/wiki/AT&T) Leveling...

Service Provider Type

...Nt1330 Service Provider Types RBOCS Regional Bell Operating Companies (RBOCS) was formed in 1984 due to the breakup of AT&T based on a restructure agreement. RBOCs were organized into seven regional Bell holding companies called Ameritech, Bell Atlantic, Bell South, Nynex, Pacific Telesis, Southwestern Bell, and US West. The BOCs were given the right to provide local phone service while AT&T was allowed to retain its long-distance service. RBOCs are progressively making available new telephone carrier technologies such as ISDN and DSL. (Margaret Rouse, 2008) LECS & ILECs Local exchange carriers (LECs) are separated into mandatory LECs (ILECs) and competitive LECs (CLECs).These carriers use the public switched telephone network system for accessing consumers. Unbundling the network helps to create the ability for CLECs to compete with ILECs. This is discussed as local-loop unbundling (LLU or LLUB). MSO Multiple system operators (MSO) are operators of multiple cable television systems. The majority of system operators run cable systems in more than one community. Cable companies offer and promote television services to consumers using radio frequency over HFC hybrid fiber copper and radio frequency over glass networks. ISP ISP is an internet service provider company the offers access to the Internet.

The seven original regional Bell operating companies were Ameritech, Bell Atlantic, BellSouth, NYNEX, Pacific Bell, Southwestern Bell, and US WEST. It is important in telecommunications because RBOCs are generally in competition for digital data and Internet traffic with wireless service providers and cable TV companies. RBOCs are gradually making available new telephone carrier technologies such as ISDN and DSL. * ILEC: Incumbent Local Exchange Carrier * Is a local telephone company in the United States that was in existence at the time of the breakup of AT&T into the Regional Bell Operating Companies (RBOCs), also known as the "Baby Bells."

Cellphone Industry

...companies and the consumers. With the information from market analysts, alongside the opinions of many involved, the fact of the matter is that there is an impact on every decision made within this mobile market, which will affect the United States in the long run . As we can tell by the history of the rise and fall of cell phone competition in the United States, we started out with numbers of telephone companies, maintaining a healthy competition. However as time passed by, especially in the case of the original AT&T, it all ended up with one company eating up the rest, achieving absolute control over the market. In this particular instance, the original AT&T was forced to split into seven “Baby Bells,” by the United States Department of Justice in a long-running antitrust suit. While this stimulated a growth in competition and awareness of possibilities within the industry, all but one “Baby Bell,” Bell Atlantic, merged together to recreate the behemoth that was AT&T. Luckily, Bell Atlantic grew to become Verizon Wireless, preserving a sense of competition in a vastly unsaturated mobile market. In the market of today, these four players reign supreme, and because of this they have the ability to affect the market as they...

...will limit my discussion to what had been known as “phone service” and not broadcast entities (TV, radio, etc...) nor shall I dwell on the so-called Cable industry. The analysis shall also be primarily focused on the domestic market. Throughout the world, historically the communication industry has overwhelmingly been a monopoly. This was also true in the United States. As AT&T evolved from the late 19th century, except for a year as a nationalized company, existed as a national monopoly. In the so- called Progressive era of the 1910’s, the idea that a natural monopoly would be more efficient and economical than competing systems took hold. The idea of universal service, with rural rates being lower than urban rates (price discrimination). While never a “true” monopoly, with its substantial market share, and restrictions on connecting non-Western Electric equipment to its network, AT&T operated as one. The barriers to entry were primarily economic, the expensive right-of-way access and materials for wired connectivity being first among them. The restriction of un approved devices not being allowed on the AT&T network, limited interconnecting between competitors as well as additional connection & maintenance fees contributed to its dominance. As a monopoly, there were limited phone styles, and little need for deep price reduction through economy of scale or innovation, though state commissions regulated rates. The upside of the additional revenue, Bell Laboratories had been able...

AT&T monopolized the telecommunication industry until the United States took them to court for antitrust and won. AT&T was broken up into eleven smaller companies, call Baby Bells. One of the companies that derived from this law suit was the Regional Bell Operating Company or RBOC. RBOC was a term that described one of the US telephone companies that provided telephone, telegraph, and long distance to the consumers. RBOC is part of a local exchange carrier allowed to compete for business. RBOC services internet service which in turn dealt with digital data. The merging companies provided different types of service based on the Telecommunication Act of 1996. ILEC or incumbent local exchange carrier is a telephone company that provided local telephone communications before the ruling to break up the Ma Bell Company.
