Question

Provide two different examples of how research uses hypothesis testing.

Answer 1

Ans) 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.

- A test of a statistical hypothesis, where the region of rejection is on both sides of the sampling distribution, is called a two-tailed test. For example, suppose the null hypothesis states that the mean is equal to 10. The alternative hypothesis would be that the mean is less than 10 or greater than

- One Sample Hypothesis Testing Examples:
The mean population IQ is 100 with a standard deviation of 15. Step 1: State the Null hypothesis. The accepted fact is that the population mean is 100, so: H0: μ=100. The fact that we are looking for scores “greater than” a certain point means that this is a one-tailed test.
