A one-sample hypothesis test can involve a single population parameter such as the mean or standard deviation.

Step 1: State the null and alternative hypotheses. The null hypothesis (H0) assumes that there is no significant difference between the sample and population parameter, while the alternative hypothesis (Ha) assumes that there is a significant difference.

Step 2: Choose the significance level (alpha). This determines the probability of rejecting the null hypothesis when it is true. Commonly used values for alpha are 0.05 or 0.01.

Step 3: Collect the sample data. This involves gathering data from a representative sample of the population.

Step 4: Calculate the test statistic. The test statistic depends on the parameter being tested (mean or standard deviation) and the type of data (normally distributed or not).

Step 5: Determine the critical value or p-value. The critical value is compared to the test statistic to determine if the null hypothesis should be rejected. The p-value is the probability of obtaining a test statistic as extreme as the one observed, assuming the null hypothesis is true.

Step 6: Make a decision. If the test statistic falls in the rejection region (beyond the critical value) or the p-value is less than the significance level, the null hypothesis is rejected. Otherwise, the null hypothesis is not rejected.

Step 7: Draw conclusions. Based on the decision made in step 6, conclusions can be drawn about the population parameter being tested.

In conclusion, a one-sample hypothesis test can involve a single population parameter such as the mean or standard deviation, and it follows a series of steps to determine if there is a significant difference between the sample and population parameter.
