Question

A marketing researcher would like to compare the mean amounts that men and
women spend on Christmas gifts. Independent random samples were taken from
each group. He would like to conduct a test to determine if women spend more on
average. If the null hypothesis is Ho : µM - µf = 0, what is the alternative
hypothesis?

Expert Solution

Step 1

Null and alternative hypotheses:

Null hypothesis:

Null hypothesis is a statement which is tested for statistical significance in the test. The decision criterion indicates whether the null hypothesis will be rejected or not in the favor of alternative hypothesis. In other words, it can be said that, the null hypothesis is a statement which indicates the relationship between statistical measurements, distributions or categories. More often, null hypothesis states no significance relationship between variables or populations. But, null does not indicate “0” all the time.

Alternative hypothesis:

Alternative hypothesis is contradictory statement of the null hypothesis.
