What is p-value in hypothesis testing?
In statistics, the p-value is
the probability of obtaining results at least as extreme as the observed results of a statistical hypothesis test
, assuming that the null hypothesis is correct. … A smaller p-value means that there is stronger evidence in favor of the alternative hypothesis.
What is hypothesis testing explain with example?
Hypothesis testing is
used to assess the plausibility of a hypothesis by using sample data
. The test provides evidence concerning the plausibility of the hypothesis, given the data. Statistical analysts test a hypothesis by measuring and examining a random sample of the population being analyzed.
What are some examples of how hypothesis testing can be applied in everyday life?
Hypothesis tests are often used in clinical trials to determine whether some new treatment, drug, procedure, etc. causes improved outcomes in patients. For example,
suppose a doctor believes that a new drug is able to reduce blood pressure in obese patients
.
How do we write a hypothesis?
- Don't just choose a topic randomly. Find something that interests you.
- Keep it clear and to the point.
- Use your research to guide you.
- Always clearly define your variables.
- Write it as an if-then statement. If this, then that is the expected outcome.
On what basis a hypothesis is accepted or rejected?
If the sample does not support the null hypothesis, we reject it on the probability basis and accept the alternative hypothesis.
If the sample does not oppose the hypothesis
, the hypothesis is accepted.
What does the Z test tell us?
Z-test is a statistical test to
determine whether two population means are different when the variances are known and the sample size is large
. Z-test is a hypothesis test in which the z-statistic follows a normal distribution. … Z-tests assume the standard deviation is known, while t-tests assume it is unknown.
