In order to assess this evidence, we need to find how likely it is that in a sample of 250 we will find that the mean number of hours per week worked by the corporate employees is as high as 47 if the true mean is 40.
<h3>What is hypothesis testing?</h3>
In hypothesis testing, in order to assess the evidence as true or not, we need to find out how likely it is to get data like those that are observed for any claim that is observed as true.
For example, regarding this question, there can be two hypotheses/ claims i.e.:
Claim 1: The average time of work for a full-time corporate employee per week is 40 hours.
Claim 2: The average time of work for a full-time corporate employee per week is more than 40 hours.
So, to find out if any of these claims are valid, research is done and the evidence is assessed by following the above-answered way.
