Based on Fly-ash bricks and clay bricks the data collected, Data will be collected through questionnaires and personal interviews targeting residential building and infrastructure projects. This research paper presents a comparison of fly-ash bricks and clay bricks. But due to less awareness of fly ash bricks the different agencies of the construction wing using clay bricks. Fly-ash Bricks is low value and high volume product and transporting it over long distances is uneconomical. The fly ash bricks are comparatively lighter in weight and stronger and less costly than common clay bricks. It is green and environmentally friendly material. Fly ash brick is a really good option against Clay brick. Fly-ash bricks are slow but surely replacing conventional clay bricks for wall constructions. This paper include the introduction, steps of hypothesis testing, function of hypothesis and testing of hypothesis.įly-ash bricks are well known bricks. It has been rightly said that “You torture the data until they confess”. Hypothesis testing shows whether the hypothesis should be accepted or rejected. There exist a number of statistical tools like ttest, F-test, chi-square test, D-W test, etc., to test the validity of hypothesis. After getting the results, the researcher tests whether the collected facts support the hypothesis formulated or not. There are four steps in hypothesis testing. There are two types of hypothesis which are called the Null Hypothesis and the Alternative Hypothesis. Hypothesis brings clarity, specificity and focus to a research problem. A researcher cannot proceed in the research work without formulating one or more than one hypothesis. It occupies a very small space in the thesis. Its main function is to suggest new experiments and observations. Hypothesis is usually considered as the principal instrument in research.
