Question

When stating the null and alternative hypotheses, the hypotheses are: Select one: a. Always about the parameter only b. Always about the statistic only c. Always about both the statistic and the parameter d. Sometimes about the statistic and sometimes about the parameter

Answer 1

Answer:

When stating the null and alternative hypotheses, the hypotheses are always about the parameter only.

Option: (a)

Explanation:

• When two variables have no statistical identity then it is known as the null hypothesis and the one with the statistical relation between the variables is the alternative hypothesis.

• While stating this hypothesis one must be concerned about the parameters. Parameter defines the boundary or the hypothesis to be true or invalid.

• Generally, the hypothesis test is done to test if a population parameter is different to a hypothesized value which we have set.
