Alternative Hypothesis (H1)

In hypothesis testing, . If the data are sufficiently strong to reject the null hypothesis, then the null hypothesis is rejected in favor of an alternative hypothesis. For instance, if the null hypothesis were that µ1= µ2 then the alternative hypothesis (for a two-tailed test) would be µ1 ≠ µ2.
So, we accept the alternative hypothesis, if the Null hypothesis is rejected.

The Null Hypothesis (H0)

The null hypothesis is an hypothesis about a population parameter. The purpose of hypothesis testing is to test the viability of the null hypothesis in the light of experimental data. Depending on the data, the null hypothesis either will or will not be rejected as a viable possibility.

The null hypothesis is often the reverse of what the experimenter actually believes; it is put forward to allow the data to contradict it.

Aim of Research in Education

The aim of research in education—and public interest research in particular—is to offer a response to challenging problems and advance a sound and coherent evidentiary base on matters of human development broadly defined. Public interest research requires the researcher to negotiate tensions across the humanistic, scientific, and engineering traditions that influence scholarship in education.

GPRS

General Packet Radio Services (GPRS) is a packet-based wireless communication service that promises data rates from 56 up to 114 Kbps and continuous connection to the Internet for mobile phone and computer users.

MMS

Multimedia Messaging Service (MMS) is a new standard in mobile messaging. Like SMS, MMS is a way to send a message from one mobile to another. The difference is that MMS can include not just text, but also sound, images and video.

Formats that can be embedded within MMS include:

• Text (formatted with fonts, colours, etc)
• Images (JPEG, GIF format)
• Audio (MP3, MIDI)
• Video (MPEG)

Packet Switching

Packet switching is similar to message switching using short messages. Any message exceeding a network-defined maximum length is broken up into shorter units, known as packets, for transmission; the packets, each with an associated header, are then transmitted individually through the network. The fundamental difference in packet communication is that the data is formed into packets with a pre-defined header format.

SMS

The acronym SMS stands for Short Message Service. SMS is also often referred to as texting, sending text messages or text messaging. The service allows for short text messages to be sent from one cell phone to another cell phone or from the Web to another cell phone(free SMS, but sometimes charges are put on the recipents). Including spaces, text messages can’t exceed 160 characters.

Public Switched Telephone Network (PSTN)

Public switched telephone network abbreviated as PSTN ,in general, is the normal phone network, or land line. PSTN is a hard wired connection which on industrial premises is usually routed through the switchboard.

Recommendations

· InstaPhone cellular network service provider should change their cellular service from Time Division Multiple Access (TDMA) based technology to Global System for Mobile communication (GSM) based technology as Paktel did. As it is readily being accepted by the people due to its SIM based GSM technology.

· SIM based connections bear many advantages. e.g. these are easily available not only from respective offices but also from the ordinary shops in the market; it may store almost 250 contact numbers in it; it is easily installable to other cell device, any time whenever user wants, and many more…

· People are not attracted when service providers introduce new packages because of the

(a) package activation charges. For instance, when user activates UCircle package of Ufone, it deducts 50 rupees from the account which of course discourages a user from package activation and

(b) Some cellular service providers offer too many packages due to which mobile users are puzzled and do not tend to activate packages. In this regard service providers should adopt the policy of simplicity of packages like Ufone

· Cellular networks should avoid deducting the hidden charges as like Al-Warid. Al-Warid cellular service provider does not deduct hidden charges but shows its open rates including all the taxes. While other service providers deduct hidden chargers even on account recharge. This seems to be very annoying to the mobile users.

· Mobilink should improve its communication servers. Research study indicates that Mobilink server becomes down particularly on Eid-Days. Users most often face Instant Connectivity problems. Some users of Mobilink are also complaining for high rates. Though users do not prefer to change their current cellular services but low call rates produce attraction for attracting new customers.

· Ufone cellular service provider should improve its voice quality and accessibility problems particularly in the rural areas. Most of the Ufone mobile users are complaining for signal problems even in the city areas that caused disturbance in the voice quality. If problem remains the same, people may choose for other cellular networks.

· Telenor should improve their SMS services particularly on Eid-days. Mobile users receive SMSs more than one time which annoy them very much.

Conclusion

The null and alternative hypotheses were suggested as follows:

H0: Users prefer mobile phone services for low call rates.

H1: Users do not prefer mobile phone services for low call rates

On the basis of analysis of research, the null hypothesis is rejected and alternative is accepted, and it is concluded that users do not prefer mobile phone services for low call rates.

Also

H0: Users do not prefer mobile phone services for instant connectivity

H1: User prefer mobile phone services for instant connectivity

On the basis of analysis of research, the null hypothesis is rejected and alternative is accepted, and it is concluded that user prefer mobile phone services for instant connectivity.

Analysis of Research Study

Research study shows users’ behavior about how they elicit their preferences for either using the services of current cellular network or change for others. Research study shows this trend in manifold ways.

· It shows that most of the people left Analog Mobile Phone System (AMPS) or Time Division Multiple Access (TDMA) based cellular networks for Global System for Mobile Communication (GSM) based cellular networks. GSM based cellular network services are readily being accepted by the mobile phone users due to SIM technology.

· Most of the cell users are not attracted by the customized packages introduced by different cellular service providers, rather mostly purchase their connections because of their relatives in order to avail low call charges.

· Mobile users showed Instant Connectivity as their preferences at first priority. Similarly Low Call Rates at second priority, Voice Quality at 3rd priority, Accessibility at 4th, Low SMS Rates at 5th and Internet Connection at 6th priority.

· Though people will not leave their current connection for low call rates, but if they faced problems in other services like instant connectivity, voice quality and accessibility etc… they will probably tend to change their current connections for other cellular network services.
