Is the average number of television watched per evening in Australia less than in Britain Null and Alternative Hypothesis required?
Null hypothesis: the number of TVs watched per evening in Australia and the UK are the same.Alternative hypothesis: the number of TVs watched per evening in Australia are fewer than in the UK.
The hypotheses should actually make clear whether the comparison is between the length of time that the TV programme is viewed, or number of programmes watched, and also whether a family of four watching together counts as 1 unit or 4. Also, what do you do with a TV set which is on but is not being watched seriously - my kids do it all the time!

What if hypothesis is not supporter by the data has been collected and analyzed?
When a hypothesis is not supported by data, two possibilities exist. The hypothesis can either be rejected and a new one is formulated, or more data is required to retest the hypothesis.
What does it mean when large amounts of data support a hypothesis?
When large amounts of data support a hypothesis, it suggests that there is a strong correlation between the variables involved, indicating that the hypothesis may be valid. This accumulation of evidence can enhance the reliability and credibility of the hypothesis, leading researchers to consider it a potential explanation for the observed phenomena. However, it's essential to remain cautious, as correlation does not imply causation, and further investigation is often required to establish a definitive relationship.
Why are repeated trials required before accepting a hypothesis are true?
They're required because a group of scientist can put down false data. So this means that other groups have to be able to find the exact data that the other group of scientist did.

What does the word experiment mean?
An experiment is an investigation or test that is required to either prove or disprove a hypothesis(an educated guess or a thought anwer to a question that is unproven). Simply put an experiment is a test that is carried out to find a solution to a problem.
What is the difference between a test statistic and a critical value?
A test statistic is a value calculated from a set of observations. A critical value depends on a null hypothesis about the distribution of the variable and the degree of certainty required from the test. Given a null hypothesis it may be possible to calculate the distribution of the test statistic. Then, given an alternative hypothesis, it is may be possible to calculate the probability of the test statistic taking the observed (or more extreme) value under the null hypothesis and the alternative. Finally, you need the degree of certainty required from the test and this will determine the value such that if the test statistic is more extreme than the critical value, it is unlikely that the observations are consistent with the hypothesis so it must be rejected in favour of the alternative hypothesis. It may not always be possible to calculate the distribution function for the variable.
What causes a hypothesis to be rejected?
A hypothesis will be rejected if it fails the necessary testing required for it to become a scientific theory.

If Relationship between statistical significance and rejectingaccepting an hypothesis?
I believe you asked for the relationship between "statistical significance" and hypothesis testing. In hypothesis testing, we state the null and alternative hypothesis, then in the traditional method, we use a test statistic and a significance level, alpha, to decide whether to accept or reject the null hypothesis in favor of the alternative. If our test statistic falls in the reject area (critical region) of the sampling distribution, then we reject the null hypothesis. If not, we accept it. There is the second method, the p-value method, which is similar in that an alpha value has to be selected. Now, the term "statistical significant result", as used in statistics, means a result (mean value, proportion or variance) from a random sample was not likely to be produced by chance. When we reject the null hypothesis in favor of the alternative, we indicate our data supports an alternative hypothesis, so our result is "statistically significant." Let me use an example. Generally workers arrive at work a few minutes more or less than required. Our null hypothesis will be an average lateness of 5 minutes, and our alternative hypothesis will be greater than 5 minutes. Our data shows an average lateness of 12 minutes, and our test statistic, taking into account the variance and sample size, and our chosen alpha level, concludes that we reject the null hypothesis, so the 12 minute average is a significantly significant result because it supported rejection of the hypothesis. The problem is that significant, in common usage, means important or meaningful, not trivial or spurious. The sample used to calculate late time may have been not randomly chosen, more people come to work late in bad weather. The sample is to make inferences on the a general population, but there is no static population in this case, as a company hires and fires employees. So, since our data is flawed, so can our conclusions. Used as a technical term in statistics, statistical significance has a much more rigorous and restricted meaning, which can lead to confusion.
