Question

In a statistical hypothesis testing scenario, what is step 1 of 5, specifically concerning stating hypotheses in terms of the standard deviation, rounding to four decimal places when necessary?

Answer 1

Step 1 in a statistical hypothesis testing scenario involves stating an appropriate null hypothesis.

Step-by-step explanation:

In a statistical hypothesis testing scenario, step 1 involves stating an appropriate null hypothesis.

For example, if we are testing whether the standard deviation of Student 1's test scores is different from Student 2's scores, the null hypothesis could be that the standard deviations are equal.

H0: σ1 = σ2

Where σ1 is the standard deviation of Student 1's test scores and σ2 is the standard deviation of Student 2's test scores.
